dstRoiSize   Destination image ROI size.
dstStep   Destination buffer step size (width of the buffer in bytes).
maskSize   Specifies the size of a mask used in calculations.
pDst   Pointer to a location in a destination buffer.
pSrc   Pointer to a location in a source buffer.
srcStep   Source buffer step size (width of the buffer in bytes).


These functions step through an ROI in a source buffer, apply a high-pass operator to the source data, and write the filtered data to a destination buffer.

The functions use either a 3X3 or a 5X5 kernel.
