Content-based image retrieval is a method for retrieving images from databases by using the actual content of images. Given an input query image, images returned from the database are those that look visually similar to the query, or those that have similar features to the query.
Content-based image retrieval (CBIR), also known as query by image content (QBIC) and content-based visual information retrieval (CBVIR) is the application of computer vision techniques to the image retrieval problem, that is, the problem of searching for digital images in large databases. (see this survey 1 for a recent scientific overview of the CBIR field). Content based image retrieval is opposed to concept based approaches. wikipedia
