Sample
Example
CuviImage* gimg = new CuviImage(size, depth, nChannels);
Cuvi64f* mean = new Cuvi64f[nChannels];
Cuvi64f* std= new Cuvi64f[nChannels];
//Upload input data
gimg->upload(hostImg->imageData, hostImg->widthStep);
//Returns mean as well as standard deviation image pixel values
cuvi::arithmeticLogical::meanStdDev(gimg, &mean, &std);
