MaxIndx

If there are several maxima in the selected region of interest, the function returns one on the top leftmost position.

The scratch buffer is required by the functions.

Common parameters for nppiMaxIndx functions include:

Parameters
pSrcSource-Image Pointer.
nSrcStepSource-Image Line Step.
oSizeROIRegion-of-Interest (ROI).
pDeviceBufferPointer to the required device memory allocation, Scratch Buffer and Host Pointer Use nppiMaxIndxGetBufferHostSize_XX_XXX to determine the minium number of bytes required.
pMaxPointer to the computed max result.
pIndexXPointer to the X coordinate of the image max value.
pIndexYPpointer to the Y coordinate of the image max value.
Returns
