Detailed Description

Compare the pixels of an image with a constant value and create a binary result image.

In case of multi-channel image types, the condition must be fulfilled for all channels, otherwise the comparison is considered false. The "binary" result image is of type 8u_C1. False is represented by 0, true by NPP_MAX_8U.

Common parameters for nppiCompareC functions include:

Parameters

pSrc	Source-Image Pointer.
nSrcStep	Source-Image Line Step.
nConstant	constant value for single channel functions.
pConstants	pointer to a list of constant values, one per color channel for multi-channel functions.
pDst	Destination-Image Pointer.
nDstStep	Destination-Image Line Step.
oSizeROI	Region-of-Interest (ROI).
eComparisonOperation	Specifies the comparison operation to be used in the pixel comparison.
nppStreamCtx	Application Managed Stream Context.

Returns

Image Data Related Error Codes, ROI Related Error Codes
