MATLAB CVIP Toolbox Functions
Band
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.
