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.
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. |
