                        const CuviImage& blue,
                        CuviImage& dst,
                        const CuviStream& stream = CuviStream());

Parameters

Name Type Description
red const CuviImage& Red channel input image
green const CuviImage& Green channel input image
blue const CuviImage& Blue channel input image
dst const CuviImage& 3-channel output Image
stream const CuviStream& GPU stream ID for execution

Image Type Support

Input Output
8uC1 x 3 8uC3
16uC1 x 3 16uC3
32fC1 x 3 32fC3

Sample

Example

//Three single channel images
CuviImage gr = cuvi::io::loadImage(path,CUVI_LOAD_IMAGE_GRAYSCALE);
CuviImage gg = cuvi::io::loadImage(path,CUVI_LOAD_IMAGE_GRAYSCALE);
CuviImage gb = cuvi::io::loadImage(path,CUVI_LOAD_IMAGE_GRAYSCALE);

//A single color image for storing output
CuviImage gout;
	
//Merge R, G and B images into a single colored image
cuvi::colorOperations::channelMerge(gr,gg,gb,gout);
