Bag-Of-Feature (BoF) is another kind of visual feature descriptor which can be used in CBIR applications. Color histograms, color moments, dominant color, scalable color, shape contour, shape region, homogeneous texture, texture browsing, and edge histogram are some of the popular descriptors that are used in CBIR applications. Image digestion is describing an image using low level features such as color, shape, and texture while removing unimportant details.
But almost all the approaches require an image digestion in their initial steps.
There are a number of approaches available to retrieve visual data from large databases.
