Major Operation Models

Most oneIPL 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 color conversion functions, which process three channels together.

oneIPL image processing functions can be divided by two major models of operation:

• Point operations: functions operate on one pixel to compute the result, for example, normalize

• Neighborhood operations: functions operate on a group of pixels, for example, gaussian
