Sample
Example
CuviImage* gimg = new CuviImage(size, depth, nChannels);
Cuvi32u* count = new Cuvi32u[nChannels];
Cuvi32f lowerBound = 25;
Cuvi32f upperBound = 100;
//Upload input data
gimg->upload(hostImg->imageData, hostImg->widthStep);
//Returns number of pixels within the given intensity range
cuvi::arithmeticLogical::countInRange(gimg, count, lowerBound, upperBound);
