2020-12-03 08:07:54 -0600	marked best answer	Pixel-wise matrix multiplication I want to multiply every pixel in an image with a 3x3 matrix, treating every pixel as a 3D-vector of colors. In mathematical terms the operation would be something like: u = M v where u is the resulting pixel value, M the (3x3) matrix, and v the original pixel value. I have searched the documentation but have not been able to find a way to do this in OpenCV. Does anybody have any suggestions?
