MATLAB CVIP Toolbox Functions

The band category contains functions useful for multi-band images, such as RGB color images. In the case of a three band color image, we have a separate matrix for each of the red, green and blue image bands. The two functions in this category allow the user to extract individual image bands for processing, and then to combine the separate bands into multi-band images. They are useful for many types of color, or multi-band, image processing algorithms. For example, for contrast enhancement of color images we often perform a color transform to decouple the color and brightness information, and then process the brightness and the color information separately before performing the inverse transform to create the enhanced image.
