Example
//Three single channel images
CuviImage* gr = new CuviImage(size,r->depth,r->nChannels);
CuviImage* gg = new CuviImage(size,g->depth,g->nChannels);
CuviImage* gb = new CuviImage(size,b->depth,b->nChannels);
//A single color image for storing output
CuviImage* gout = new CuviImage(size,r->depth,3);
//Populate the GPU images with pixel data
gr->upload(r->imageData,r->widthStep,st);
gg->upload(g->imageData,g->widthStep,st);
gb->upload(b->imageData,b->widthStep,st);
//Merge R, G and B images into a single colored image
cuvi::colorOperations::channelMerge(gr,gg,gb,gout);
