Regions of Interest

Many Intel® IPP image processing functions operate with a region of interest (ROI). These functions include an
R
descriptor in their names.
A ROI can be the full image or a subset. This can simplify thread or cache blocking.
Many functions sample a neighborhood and cannot provide values for an entire image. In this case a ROI must be defined for the subset of the destination image that can be computed.
