Most Intel IPP image processing functions perform identical and independent operations on all channels of the processed image except for alpha channel. It means that the same operation is applied to each channel, and the computed results do not depend on values of other channels. Some exceptions include the ippiFilterMedianColor function and color conversion functions, which process three channels together.
Intel IPP image processing functions can be divided by two major models of operation:
