GazoPa is an image search engine by Hitachi that uses features from an image to search for and identify similar images. There are abundant quantities of images on the web, however many of these simply cannot be described by keywords, keywords are not sufficient as conditions for image searches. Since GazoPa uses image features such as a color or a shape to search other similar images, a vast range of images can be retrieved from the web. In addition to images found using keyword searches, GazoPa enables the use of users’ own photos and drawings, and images found on the web, as search keys to locate similar images. GazoPa can support not only photo but also the search of video thumbnail. GazoPa lets users find favorite video from similarity of video thumbnail.
