Can you use cv::integral on a BGR Mat? I want to calculate the integral image for each channel. Do I need to split the channels and call cv::integral for each channel or can I just use the function with a 3 channel Mat?
I am currently using this utility class that helps but I'm not sure if its made to handle multichannel Mats?
