Detailed Description

Threshold image pixels.

Common parameters for nppiThreshold non-inplace and inplace functions include:

Parameters
pSrcDstIn-Place Image Pointer for inplace functions.
nSrcDstStepIn-Place-Image Line Step for inplace functions.
pSrcSource-Image Pointer for non-inplace functions.
nSrcStepSource-Image Line Step for non-inplace functions.
pDstDestination-Image Pointer for non-inplace functions.
nDstStepDestination-Image Line Step for non-inplace functions.
oSizeROIRegion-of-Interest (ROI).
nThresholdThe threshold value.
eComparisonOperationThe type of comparison operation to be used. The only valid values are: NPP_CMP_LESS and NPP_CMP_GREATER.
nppStreamCtxApplication Managed Stream Context.
Returns
Image Data Related Error Codes, ROI Related Error Codes, or NPP_NOT_SUPPORTED_MODE_ERROR if an invalid comparison operation type is specified.
