Sample
Example
CuviImage* gimg = cuvi::io::loadImage(path);
Cuvi32u* count = new Cuvi32u[gimg.channels()];
const Cuvi32f lowerBound = 25.0f;
const Cuvi32f upperBound = 100.0f;
//Returns number of pixels within the given intensity range
cuvi::imageStatistics::countInRange(gimg, count, lowerBound, upperBound);
