The result of a neighborhood operation is based on values of a certain group of pixels, located near a given input pixel. The set of neighboring pixels is typically defined by a rectangular mask (or kernel) and anchor cell, specifying the mask alignment with respect to the position of the input pixel.
The Intel IPP functions that process a neighborhood operate on the assumption that all referred points of the image are available. To support this mode, the application must check that ROI parameters passed to the function have such values that all processed neighborhood pixels actually exist in the image.
