Computer vision tools for fidding images and vidio sequences

Аннотация

Very large collections of images are now common. Indexing and searching such collections using indexing languages is difficult. Com-puter vision offers a variety of techniques for searching for pictures in large collections. Appearance methods compare images based on the overall content of the image using such criteria as similarity of color histo-grams, texture histograms, spatial layout, and filtered representations. Finding methods concentrate on matching subparts of images, defined in a variety of ways, in the hope of finding particular objects. These ideas are illustrated with a variety of examples from the current literature.
