many pixel accesses on the image you can also use the cv Mat_ convenience type. This is nothing more than a typed thin wrapper.. that all accesses to image pixels are appropriately typed Mat_ Vec3b U reinterpret_cast Mat_ Vec3b I You can then freely use.. are appropriately typed Mat_ Vec3b U reinterpret_cast Mat_ Vec3b I You can then freely use U i j and always get a 3 tuple..
