This section describes the Intel® IPP image processing functions that perform linear and non-linear filtering operations on an image.
You can use filtering in image processing operations like edge detection, blurring, noise removal, and feature detection.
Most filtering functions operate with regions of interest (ROI). The size of the source image ROI is equal to the destination image ROI size
dstRoiSize. Most functions use different source and destination image buffers. These functions are not in-place.
