Example
//A single color image
CuviImage *gimg = new CuviImage(_size,img->depth,img->nChannels);
//Three single channel images for storing output
CuviImage *gr = new CuviImage(_size,img->depth,1);
CuviImage *gg = new CuviImage(_size,img->depth,1);
CuviImage *gb = new CuviImage(_size,img->depth,1);
//Populate the GPU image with pixel data
gimg->upload(img->imageData,img->widthStep);
//Split into R, G and B channels
CuviStatus st = cuvi::colorOperations::channelSplit(gimg,gr,gg,gb);
