An image retrieval system is a computer system for browsing, searching and retrieving images from a large database of digital images. It can be based on a textual description of the images in the database, but the manual annotation of the images in time-consuming and ambiguous. Therefore, content-based image retrieval (CBIR) aims at avoiding a textual description and retrieving images based on their visual similarity to a user-supplied query image instead.
