| | The Bayesian Image Retrieval System, PicHunter: Theory, Implementation and Psychophysical Experiments |
 | | Users search for images that belong to a prototypical category, e.g., ``dogs'', ``skyscrapers'', ``kitchens'', or ``scenes of basketball games''; in some sense, when a user is asked to find an image that is adequately similar to a target image, the user embarks on a category search. |
 | | This type of search is valuable for testing purposes (see section V) and occurs, for example, when checking if a particular logo has been previously registered, or when searching for a specific historical photograph to accompany a document, or when looking for a specific painting whose artist and title escapes the searcher's memory. |
 | | In a typical application, a user may start a search for a wallpaper geometric pattern with pastel colors, but the goal may change several times during the search, as the user navigates through the database and is exposed to various options. |
