Primitives for computing the amount of pixels that fall into the specified intensity range. More...

CountInRange

The lower bound and the upper bound are inclusive.

The functions require additional scratch buffer for computations.

Common parameters for nppiCountInRange functions include:

Parameters
pSrcSource-Image Pointer.
nSrcStepSource-Image Line Step.
oSizeROIRegion-of-Interest (ROI).
pCountsPointer to the number of pixels that fall into the specified range.
nLowerBoundLower bound of the specified range.
nUpperBoundUpper bound of the specified range.
pDeviceBufferPointer to the required device memory allocation, Scratch Buffer and Host Pointer.
nppStreamCtxApplication Managed Stream Context.
Returns
Image Data Related Error Codes, ROI Related Error Codes, or NPP_RANGE_ERROR if the lower bound is larger than the upper bound.
