HistogramEven

The histogram is computed according to the ranges provided in $pLevels$ .

The histogram $pHist[k]$ is defined as the total number of pixels that fall into the range: $pLevels[k] <= pSrc(j, i) < pLevels[k+1]$ . The number of the histogram bins is $nLevel - 1$ . The functions require additional scratch buffer for computations.

Common parameters for nppiHistogramEven functions include:

Parameters

pSrc	Source-Image Pointer.
nSrcStep	Source-Image Line Step.
oSizeROI	Region-of-Interest (ROI).
pHist	Pointer to array that receives the computed histogram. The array must be of size nLevels-1.
pLevels	Pointer to array containing the level sizes of the bins. The array must be of size nLevels.
nLevels	Number of levels in histogram.
pBuffer	Pointer to appropriately sized (nppiHistogramRangeGetBufferSize_XX_XXX) scratch buffer.

Returns: Image Data Related Error Codes, ROI Related Error Codes
