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.

Product and Performance Information

1

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
