Class NPPNativeMethods.NPPi.FilterThresholdAdaptiveBoxBorder

Computes the average pixel values of the pixels under a square mask with border control. 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. Once the neighborhood average around a source pixel is determined the souce pixel is compared to the average - nDelta and if the source pixel is greater than that average the corresponding destination pixel is set to nValGT, otherwise nValLE. Currently only the NPP_BORDER_REPLICATE border type operation is supported.
