In the fields of electrical engineering and computer science, the image processing concept is composed of any signal processing technique, where the input is represented by an image (a standalone picture or a snapshot taken from a video sequence) and the output is represented by a different image or by a set of characteristics or parameters which describe it. Most of the image processing algorithms treat the image as a bi-dimensional signal on which they apply standard signal processing techniques. The Content-Based Image Retrieval – CBIR concept is also known as Query by Image Content (QBIC) or Content-Based Visual Information Retrieval (CBVIR) and represents a solution to the problem of searching digital images in a large database. The "Content-Based" term implies that the CBIR techniques use the real image content, as opposed to the information extracted from the metadata fields, like key words, labels, tags or any other form of description associated to the image.
