Major Operation Models

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

The Intel IPP image processing functions can be broken into two major models of operation: the functions that operate on one pixel to compute the result (also known as point operations), for example, ippiAdd, and the functions that operate on a group of pixels (also referred to as a neighborhood), for example, ippiFilterBox.
