Function:Gray2rgb

Converts a gray-scale image to 3 or 4 channel image by copying the same input image to all the channels of output image. For a 4 channel output image, the alpha channel is ignored. The resultant image will still be gray (since all channels are of same value) but it will be a 3/4 channel image. For debayer, please refer to demosaicDFPD.

Function

CuviStatus gray2rgb(const CuviImage& src, CuviImage& dst, const CuviStream& stream = CuviStream()); CuviStatus gray2rgb(CuviImage& srcDst, const CuviStream& stream = CuviStream());
