dstRoiSize   Destination image ROI size.
dstStep   Destination buffer step size (width of the buffer in bytes).
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 horizontal Roberts operator to the source data, and write the filtered data to a destination buffer.

These functions provide a gross approximation of the horizontal pixel gradient.
