Class NPPNativeMethods.NPPi.ErosionWithBorderControl

Erosion computes the output pixel as the minimum pixel value of the pixels under the mask. Pixels who's corresponding mask values are zero do not participate in the minimum search.

If any portion of the mask overlaps the source image boundary the requested border type operation is applied to all mask pixels which fall outside of the source image.
