Image retrieval is a prominent area of digital image processing. Images can be retrieved from a large collection of databaseimages on the basis of text, color and structure. Content-based image retrieval uses the visual content ofimages such as color, shape, texture and spatial layout for representing and indexing the images. In a typical CBIR system, thevisual content of the images in the database are extracted and displayed by multi-dimensional feature vectors. Thefeature vector of the images in the database is a feature database. To retrieve the images, users provide theretrieval system with query images.
