Web27 de ago. de 2015 · cv::Mat is the most fundamental datatype used in OpenCV. It can be used to store 2D images with 1-4 channels of data. When your code receives a cv::Mat … WebFor example, let's say we have a 100 x 100 Mat object of type CV_8UC3. Each pixel value will take 8 bits and there will be three such values for each pixel (three channels). That takes it to 24 bits per pixel. There are 100 x 100 = 10,000 pixels in total, which means a total space of (24 x 10,000) bits = 30 kilobytes.
