Basic Tiling API

iwiTile_SetTile

Basic tiling initializer for the IwiTile structure. Use this method to set up single function tiling or tiling for pipelines with border-less functions. For functions which operate with different sizes for source and destination images use destination size as a base for tile parameters.

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.
