I have seen in other questions how to subtract a three channel matrix, but I am starting with OpenCV in C++ and my question is, I imagine, easier for the people that know...
How can I subtract one Matrix from another in OpenCV, element by element... "by hand"? Because I have tried using the functions that supposedly do this, like subtract(mat, mat2, result) but it is not working, and I don't know why, so maybe doing this operations "deeply", going element by element might help me reach the problem.
