WebTo access individual pixels, the safest way, though not the most efficient, is to use cv::Mat::at (r,c) method where r is the row of the matrix and c is the column. The template argument depends on the type of the matrix. Let us say you have a cv::Mat image. According to its type, the access method and the pixel color type will be different.
