Sample

Example

CuviImage* gimg = new CuviImage(size, depth, nChannels); Cuvi64f* max = new Cuvi64f[nChannels]; Cuvi64f* min = new Cuvi64f[nChannels]; //Upload input data gimg->upload(hostImg->imageData, hostImg->widthStep); //Returns minimum and maximum pixel value cuvi::arithmeticLogical::minMax(gimg, &min, &max);
