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
pSrcSource-Image Pointer.
nSrcStepSource-Image Line Step.
oSizeROIRegion-of-Interest (ROI).
pHistPointer to array that receives the computed histogram. The array must be of size nLevels-1.
pLevelsPointer to array containing the level sizes of the bins. The array must be of size nLevels.
nLevelsNumber of levels in histogram.
pBufferPointer to appropriately sized (nppiHistogramRangeGetBufferSize_XX_XXX) scratch buffer.
Returns
Image Data Related Error Codes, ROI Related Error Codes
