Image sharing , or photo sharing , is the publishing or transfer of digital photos online. Image sharing websites offer services such as uploading, hosting, managing and sharing of photos (publicly or privately). This function is provided through both websites and applications that facilitate the upload and display of images. The term can also be loosely applied to the use of online photo galleries that are set up and managed by individual users, including photoblogs . Sharing means that other users can view but not necessarily download images, and users can select different copyright options for their images.
117-559: Google Photos is a photo sharing and storage service developed by Google . It was announced in May 2015 and spun off from Google+ , the company's former social network . Google Photos shares the 15 gigabytes of free storage space with other Google services, such as Google Drive and Gmail . Users can upload their photos and videos in either quality setting, original or compressed (photos and videos up to 16 megapixels and 1080p resolution , respectively), that will count towards
234-922: A heat map of photo locations was added in 2020. There are issues about data sharing and exporting, such as not being able to download pictures and videos in their original quality or with all the original data, notably GPS location info. Even downloading via the Google Takeout feature results in some of the original information missing. This could potentially lead to vendor lock in if the user wants to keep using features requiring those missing pieces of data. Google Photos has three storage settings: "Storage saver" (formerly "High quality"), "Original quality" and "Express quality" (unavailable in certain locations). Storage saver includes photo and video storage for photos up to 16 megapixels and videos up to 1080p resolution (the maximum resolutions for average smartphone users in 2015). Original quality preserves
351-432: A label to instances, and models are trained to correctly predict the preassigned labels of a set of examples). Characterizing the generalization of various learning algorithms is an active topic of current research, especially for deep learning algorithms. Machine learning and statistics are closely related fields in terms of methods, but distinct in their principal goal: statistics draws population inferences from
468-421: A sample , while machine learning finds generalizable predictive patterns. According to Michael I. Jordan , the ideas of machine learning, from methodological principles to theoretical tools, have had a long pre-history in statistics. He also suggested the term data science as a placeholder to call the overall field. Conventional statistical analyses require the a priori selection of a model most suitable for
585-480: A theoretical neural structure formed by certain interactions among nerve cells . Hebb's model of neurons interacting with one another set a groundwork for how AIs and machine learning algorithms work under nodes, or artificial neurons used by computers to communicate data. Other researchers who have studied human cognitive systems contributed to the modern machine learning technologies as well, including logician Walter Pitts and Warren McCulloch , who proposed
702-505: A "Deep blue" slider feature that lets users change the color and saturation of skies, without degrading image quality or inadvertently changing colors of other objects or elements in photos. In February 2017, Google updated the "Albums" tab on the Android app to include three separate sections; one for the phone's camera roll, with different views for sorting options (such as people or location); another for photos taken inside other apps; and
819-492: A central repository for all photos or specific categories of images. "Photo Books" are physical collections of photos, offered either as softcover or hardcover albums, with Photos automatically suggesting collections based on face, location, trip, or other distinction. Towards the end of the month, Google introduced an "Archive" feature that lets users hide photos from the main timeline view without deleting them. Archived content still appears in relevant albums and in search. In June,
936-413: A central service. The downsides are that the consumer does not get the benefit of off-site backup; consumer Internet service providers (ISPs) often prohibit the serving of content both by contract and through the implementation of network filtering, and there are few quality guarantees for recipients. However, there are typically no direct consumer costs beyond the purchase of the initial software, provided
1053-439: A computation is considered feasible if it can be done in polynomial time . There are two kinds of time complexity results: Positive results show that a certain class of functions can be learned in polynomial time. Negative results show that certain classes cannot be learned in polynomial time. Machine learning approaches are traditionally divided into three broad categories, which correspond to learning paradigms, depending on
1170-444: A considerable improvement in learning accuracy. In weakly supervised learning , the training labels are noisy, limited, or imprecise; however, these labels are often cheaper to obtain, resulting in larger effective training sets. Reinforcement learning is an area of machine learning concerned with how software agents ought to take actions in an environment so as to maximize some notion of cumulative reward. Due to its generality,
1287-444: A directory-like structure in so-called "galleries". Some sites also allow users to classify images using tags to build a folksonomy . Depending on the restrictions on the set of users allowed to tag a single document and the set of tags available to describe the document, one speaks about narrow and broad folksonomies. A folksonomy is broad when there is no restriction on the set of taggers and available tags. When there are limitations,

They may also have other enhancements over free services, such as guarantees regarding the online availability of photos, more storage space, the ability for non-account holders to download full-size, original versions of photos, and tools for backing up photos. Some offer user photographs for sale, splitting
1521-414: A hierarchy of features, with higher-level, more abstract features defined in terms of (or generating) lower-level features. It has been argued that an intelligent machine is one that learns a representation that disentangles the underlying factors of variation that explain the observed data. Feature learning is motivated by the fact that machine learning tasks such as classification often require input that

A representative book on research into machine learning during the 1960s was Nilsson's book on Learning Machines, dealing mostly with machine learning for pattern classification. Interest related to pattern recognition continued into the 1970s, as described by Duda and Hart in 1973. In 1981
1755-420: A limited set of values, and regression algorithms are used when the outputs may have any numerical value within a range. As an example, for a classification algorithm that filters emails, the input would be an incoming email, and the output would be the name of the folder in which to file the email. Examples of regression would be predicting the height of a person, or the future temperature. Similarity learning
1872-426: A lot of images of a specific subject; it now makes animations from videos as well as photos (photo animations have been present since the start), displaying specific photos intermixed with short excerpts from longer videos in videos; and it now attempts to detect sideways and upside down photos and prompts the user to accept or reject a different orientation. For all of these features, Google touts machine learning does
1989-483: A low-resolution image will be sent before being updated with a higher-quality version. In April, Google added video stabilization . The feature creates a duplicate video to avoid overwriting the original clip. In May 2017, Google announced several updates to Google Photos. "Suggested Sharing" reminds users to share captured photos after the fact, and also groups photos based on faces and suggests recipients based on facial recognition. "Shared Libraries" lets two users share

Evaluated with respect to known knowledge, an uninformed (unsupervised) method will easily be outperformed by other supervised methods, while in
2340-538: A picture to a tweet without depending on another application such as TwitPic or Yfrog. As of June 2016, there were more than 500 million monthly active Instagram users. Image sharing on social news and image aggregation sites such as Reddit , Imgur , 4chan , Pinterest and Tumblr allow users to share images with a large community of users. Images are the most liked content of the aggregation and media sharing site Reddit; and according to data analyst Randy Olson as of August 2014, nearly 2/3 of all successful posts on

Some sites including Panoramio and Wikimedia Commons show their geocoded photographs on a map, helping the user find pictures of the same or nearby objects from different directions. Critics of image/photo sharing are concerned with the use of applications such as Instagram, because they believe that the behaviors portrayed on these sites could potentially be linked to the narcissism trait. Keen argues that "Self"
2691-553: A report was given on using teaching strategies so that an artificial neural network learns to recognize 40 characters (26 letters, 10 digits, and 4 special symbols) from a computer terminal. Tom M. Mitchell provided a widely quoted, more formal definition of the algorithms studied in the machine learning field: "A computer program is said to learn from experience E with respect to some class of tasks T and performance measure P if its performance at tasks in T , as measured by P , improves with experience E ." This definition of

Some sites allow you to post your pictures online and they will then project the image onto famous buildings during special events, while other sites let you insert photos into digital postcards, slide shows and photo albums and send them to others. Some free sites are owned by camera manufacturers, and only accept photos made with their hardware. In return for
3159-406: A tag can also be used as a link that when clicked will take you to the person's profile that was tagged. Most of the time photos can only be tagged by the user to uploads the photo but on some sites photos can be tagged by other users as well. These tags can be searched for across the entire Internet, on separate websites or in private data bases. They can be used for crowdsourced classification (see

The Android app and website were the first to receive the feature, with a later rollout to the iOS app. Later in March, updates to the service enabled uploading of photos in a "lightweight preview" quality for immediate viewing on slow cellular networks before a higher-quality upload later while on faster Wi-Fi. The feature also extends to sharing photos, in which
3393-443: A typical KDD task, supervised methods cannot be used due to the unavailability of training data. Machine learning also has intimate ties to optimization : Many learning problems are formulated as minimization of some loss function on a training set of examples. Loss functions express the discrepancy between the predictions of the model being trained and the actual problem instances (for example, in classification, one wants to assign
3510-531: A website. Users back up their photos to the cloud service, which becomes accessible for all of their devices. The Photos service analyzes and organizes images into groups and can identify features such as beaches, skylines, or "snowstorm in Toronto." From the application's search window, users are shown potential searches for groups of photos in three major categories: People, Places, and Things. The service analyzes photos for similar faces and groups them together in
3627-772: A zip file's compressed size includes both the zip file and the unzipping software, since you can not unzip it without both, but there may be an even smaller combined form. Examples of AI-powered audio/video compression software include NVIDIA Maxine , AIVC. Examples of software that can perform AI-powered image compression include OpenCV , TensorFlow , MATLAB 's Image Processing Toolbox (IPT) and High-Fidelity Generative Image Compression. In unsupervised machine learning , k-means clustering can be utilized to compress data by grouping similar data points into clusters. This technique simplifies handling extensive datasets that lack predefined labels and finds widespread use in fields such as image compression . Data compression aims to reduce

9243-604: The free storage tier (compressed items uploaded before June 1, 2021, along with items uploaded via Pixel phones released before that date, are unlimited). Users can expand their storage through paid Google One subscriptions. The service automatically analyzes photos, identifying various visual features and subjects. Users can search for anything in photos, with the service returning results from three major categories: People, Places, and Things. The computer vision of Google Photos recognizes faces (not only those of humans, but pets as well), grouping similar ones together (this feature
9360-405: The future is uncertain, learning theory usually does not yield guarantees of the performance of algorithms. Instead, probabilistic bounds on the performance are quite common. The bias–variance decomposition is one way to quantify generalization error . For the best performance in the context of generalization, the complexity of the hypothesis should match the complexity of the function underlying
9477-451: The idea of paying for photo storage. Sarah Mitroff and Lynn La of CNET wrote that the service's phone and tablet apps were particularly good, and that Google Photos had a more streamlined design than Yahoo 's Flickr and more organizing features than Apple's iCloud photo service. Kastrenakes described the service's May 2015 release as evidence that Google was spinning out the "best features" of its Google+ social network. He stated that
9594-424: The information in their input but also transform it in a way that makes it useful, often as a pre-processing step before performing classification or predictions. This technique allows reconstruction of the inputs coming from the unknown data-generating distribution, while not being necessarily faithful to configurations that are implausible under that distribution. This replaces manual feature engineering , and allows
9711-905: The launch of the service, Google announced that Google Photos had 100 million users, who had uploaded 3.72 petabytes of photos and videos. In May 2016, one year after the release of Google Photos, Google announced the service had over 200 million monthly active users . Other statistics it revealed was at least 13.7 petabytes of photos/videos had been uploaded, 2 trillion labels had been applied (24 billion of those being selfies), and 1.6 billion animations, collages and effects had been created based on user content. In May 2017, Google announced that Google Photos has over 500 million users, who upload over 1.2 billion photos every day. In November 2020, Google announced that more than 4 trillion photos are stored in Google Photos, and every week 28 billion new photos and videos are uploaded. At
9828-434: The machine learning algorithms like Random Forest . Some statisticians have adopted methods from machine learning, leading to a combined field that they call statistical learning . Analytical and computational techniques derived from deep-rooted physics of disordered systems can be extended to large-scale problems, including machine learning, e.g., to analyze the weight space of deep neural networks . Statistical physics
9945-543: The members is normative. Privacy activists and researchers have noted that the sharing of images on social networks may compromise the privacy of people depicted in them. Further, most current social networks afford their users little control over content that they did not post themselves. In its privacy policy , Facebook states that any information posted using its service, including images, may be used to display relevant ads to its users. Facebook utilizes automatic facial recognition software that can automatically recognize
10062-559: The name of "High quality" to "Storage saver". The move was part of an effort to reduce Google's reliance on ad-based revenue and increase subscriptions. Existing photos will remain unaffected, and new photos will count towards the user's storage quota shared across Google Drive , Gmail , and Google Photos. Owners of the Google Pixel smartphones up until the Pixel 5 will remain exempt from this change. In October 2015, five months after
10179-437: The nature of the "signal" or "feedback" available to the learning system: Although each algorithm has advantages and limitations, no single algorithm works for all problems. Supervised learning algorithms build a mathematical model of a set of data that contains both the inputs and the desired outputs. The data, known as training data , consists of a set of training examples. Each training example has one or more inputs and
10296-667: The need for instant sharing with friends and followers. In recent years, AI and machine learning have become increasingly integrated into photo sharing platforms. AI is being used to improve image quality, automatically tag images with relevant keywords, detect and filter inappropriate content, and create new effects and filters. AI has the potential to revolutionize the way people share photos, making it easier for them to share better-looking images and find relevant images. Image sharing sites can be broadly broken up into two groups: sites that offer photo sharing for free and sites that charge consumers directly to host and share images. Of
10413-406: The new sharing features announced in May began rolling out to users. In December 2018, Google doubled the number of photos and videos users can store in a private Google Photos Live Album. The number increased from 10,000 to 20,000 photos, which is equivalent to the capacity for shared albums. In September 2019, Google Photos introduced a new social media -like feature called "Memories" similar to
10530-703: The original resolution and quality of the photos and videos. Express quality includes photo and video storage for photos up to 3 megapixels and videos up to 480p resolution. For the first three generations of the Google Pixel phones, Google Photos offers unlimited storage at "Original quality" for free. The original Pixel had no limits to this offer, while the Pixel 2 and 3 only offered unlimited storage at "Original quality" for photos and videos taken before January 16, 2021, and January 31, 2022, respectively, with all photos and videos taken after those dates being uploaded at "Storage saver" instead. The Pixel 3a and onwards do not offer unlimited storage at "Original quality", with
10647-610: The output distribution). Conversely, an optimal compressor can be used for prediction (by finding the symbol that compresses best, given the previous history). This equivalence has been used as a justification for using data compression as a benchmark for "general intelligence". An alternative view can show compression algorithms implicitly map strings into implicit feature space vectors , and compression-based similarity measures compute similarity within these feature spaces. For each compressor C(.) we define an associated vector space ℵ, such that C(.) maps an input string x, corresponding to
10764-414: The photos together and suggest creating an album with them, alongside maps to show geographic travel and location pins for exact places. Users can also add text captions to describe photos. In October, Google announced multiple significant updates; Google Photos now surfaces old memories with people identified in users' recent photos; it occasionally highlights a subset of photos when a user has recently taken
10881-457: The potentiality of tracking places. Geotagging can reveal the footprints and behaviors of travelers by utilizing spatial proximity of geo-tagged photos that are shared online, making it possible to extract travel information relating to a particular location. Instagram, Flickr, and Panoramio are a few services that provide the option of geotagging images. Flickr has over 40 million geotagged photos uploaded by 400 thousand users, and still growing at
10998-503: The proceeds with the photographer , while others may use a disclaimer to reserve the right to use or sell the photos without giving the photographer royalties or notice. Some image sharing sites have begun integrating video sharing as well. With the introduction of high speed (broadband) connections directly to homes, it is feasible to share images and videos without going through a central service. The advantages of peer-to-peer sharing are reduced hosting costs and no loss of control to
11115-416: The quality of photos and videos. In May 2017, Google announced several updates to Google Photos, including reminders for and suggested sharing of photos, shared photo libraries between two users, and physical albums. Photos automatically suggested collections based on face, location, trip, or other distinction. Google Photos received critical acclaim after its decoupling from Google+ in 2015. Reviewers praised
11232-430: The rise of mobile apps and cloud storage . The advent of smartphones with high-quality cameras and the availability of cloud storage services such as Google Photos , Dropbox , and iCloud Photo Library revolutionized the way people take, store, and access their photos. Mobile apps such as Instagram , Snapchat , and TikTok emerged, offering a simple and socially focused photo sharing experience. These apps met
11349-421: The same month. Mossberg thought the face grouping feature was "remarkably accurate", but was most impressed by the subject-based grouping. He was surprised that a search for "boats" found both Cape Cod fishing boats and Venetian gondolas , but also noted errors such as a professional photograph registering as a screenshot. PC Magazine 's John C. Dvorak was concerned about the service's privacy. He
11466-411: The section on image classification ) but can also play a socio-cultural role in that they can establish neologisms , Internet memes , snowclones , slogans , catch phrases , shared vocabularies and categorizations as well as producing comedic twists, contexts and perspectives of the presented images, and hence often play a significant role in the community building and identity formation of and
11583-493: The service never became as popular as Facebook for social networking and photo sharing. Google+ offered photo storage and organizational tools that surpassed Facebook's in power, though Google+ lacked the user base to use it. By leaving the social network affiliation, the Photos service changed its association from a sharing platform to a private library platform. In December 2015, Google added shared albums to Google Photos. Users pool photos and videos into an album, and then share
11700-499: The service's poor choice of photos to animate and lack of longevity guarantees, considering the company's abrupt cancellation of Google Reader . He ultimately suggested that users instead use a portable hard drive, which he considered safer and cheap. https://linkfly.to/61027uXra6F Photo sharing While photoblogs tend only to display a chronological view of user-selected medium-sized photos, most photo sharing sites provide multiple views (such as thumbnails and slideshows ),
11817-415: The service's search function, writing that a search for "Massachusetts" "instantly brought up loads of photos of subjects". Lowensohn noted the service's speed and intelligence, especially in its ability to sort unorganized photos, as well as its photo loading times, search speeds, and simple photo editing tools. Kastrenakes compared the service's new image analysis to technology unveiled by Flickr earlier in
11934-673: The site were links to an image hosted on Imgur. Sharing images via mobile phones has become popular. Several networks and applications have sprung up offering capabilities to share captured photos directly from mobile phones to social networks. The most prominent of these is Instagram , which has quickly become the dominant image sharing-centric social network with over 500 million members. Other applications and networks offering similar service and growing in popularity include Streamzoo , Path , PicsArt , Piictu , and Starmatic . Instagram , Snapchat , and Nice are examples of photo sharing apps with millions of users. Software can be found on
12051-491: The sites that offer free photo sharing, most can be broken up into advertising-supported media plays and online photo finishing sites, where photo sharing is a vehicle to sell prints or other merchandise. These designations are not strict, and some subscription sites have a limited free version. Consumers can share their photos directly from their home computers over high speed connections through peer-to-peer photo sharing using applications. Peer-to-peer photo sharing often carries
12168-546: The size of data files, enhancing storage efficiency and speeding up data transmission. K-means clustering, an unsupervised machine learning algorithm, is employed to partition a dataset into a specified number of clusters, k, each represented by the centroid of its points. This process condenses extensive datasets into a more compact set of representative points. Particularly beneficial in image and signal processing , k-means clustering aids in data reduction by replacing groups of data points with their centroids, thereby preserving
12285-527: The space of occurrences) and the learner has to build a general model about this space that enables it to produce sufficiently accurate predictions in new cases. The computational analysis of machine learning algorithms and their performance is a branch of theoretical computer science known as computational learning theory via the Probably Approximately Correct Learning (PAC) model. Because training sets are finite and
12402-419: The structure of the data, often defined by some similarity metric and evaluated, for example, by internal compactness , or the similarity between members of the same cluster, and separation , the difference between clusters. Other methods are based on estimated density and graph connectivity . A special type of unsupervised learning called, self-supervised learning involves training a model by generating
12519-525: The study data set. In addition, only significant or theoretically relevant variables based on previous experience are included for analysis. In contrast, machine learning is not built on a pre-structured model; rather, the data shape the model by detecting underlying patterns. The more variables (input) used to train the model, the more accurate the ultimate model will be. Leo Breiman distinguished two statistical modeling paradigms: data model and algorithmic model, wherein "algorithmic model" means more or less
12636-417: The supervisory signal from the data itself. Semi-supervised learning falls between unsupervised learning (without any labeled training data) and supervised learning (with completely labeled training data). Some of the training examples are missing training labels, yet many machine-learning researchers have found that unlabeled data, when used in conjunction with a small amount of labeled data, can produce
12753-428: The tasks in which machine learning is concerned offers a fundamentally operational definition rather than defining the field in cognitive terms. This follows Alan Turing 's proposal in his paper " Computing Machinery and Intelligence ", in which the question "Can machines think?" is replaced with the question "Can machines do what we (as thinking entities) can do?". Modern-day machine learning has two objectives. One
12870-481: The updated Photos service for its recognition technology, search, apps, and loading times. Nevertheless, privacy concerns were raised, including Google's motivation for building the service, as well as its relationship to governments and possible laws requiring Google to hand over a user's entire photo history. Google Photos has seen strong user adoption. It reached 100 million users after five months, 200 million after one year, 500 million after two years, and passed
12987-509: The vector norm ||~x||. An exhaustive examination of the feature spaces underlying all compression algorithms is precluded by space; instead, feature vectors chooses to examine three representative lossless compression methods, LZW, LZ77, and PPM. According to AIXI theory, a connection more directly explained in Hutter Prize , the best possible compression of x is the smallest possible software that generates x. For example, in that model,
13104-473: The viewer through a standard web browser . Technically speaking, this may still be described as peer-to-peer (with the second peer being a web browser) but it is characteristically different as it assumes no need to download peer software for the viewer. Photos are accessed by regular URLs that standard web browsers understand natively without any further software required. Consequently, photos shared in this way are accessible not only to users who have downloaded
13221-455: The work, with no user interaction required. In November, Google released a separate app – PhotoScan – for users to scan printed photos into the service. The app, released for iOS and Android, uses a scanning process in which users must center their camera over four dots that overlay the printed image, so that the software can combine the photographs for a high-resolution digital image with the fewest possible defects. Later that month, Google added
13338-456: Was also used in this time period. Although the earliest machine learning model was introduced in the 1950s when Arthur Samuel invented a program that calculated the winning chance in checkers for each side, the history of machine learning roots back to decades of human desire and effort to study human cognitive processes. In 1949, Canadian psychologist Donald Hebb published the book The Organization of Behavior , in which he introduced
13455-481: Was founded, focusing on providing a high-quality photo sharing experience for professional photographers. SmugMug offers features such as custom photo galleries and e-commerce options. In 2003, Yahoo! Photos was one of the most popular photo sharing platforms thanks to its integration with Yahoo's email and search services. In 2004, Flickr was founded, quickly becoming popular due to its vibrant photography community and effective tagging system. The 2010s saw
13572-450: Was out of favor. Work on symbolic/knowledge-based learning did continue within AI, leading to inductive logic programming (ILP), but the more statistical line of research was now outside the field of AI proper, in pattern recognition and information retrieval . Neural networks research had been abandoned by AI and computer science around the same time. This line, too, was continued outside
13689-467: Was particularly concerned about Google's motivation for building the service, the company's relationships with existing governments, and potential laws that would require Google to provide a user's entire history of photos upon request. Dvorak compared such a scenario to inviting others to "scrounge through your underwear drawer". He criticized the service's sync functions, and preferred folders of images over an unsorted "flat database". Dvorak also highlighted
