denoise_TVL1 doens't work in python3 but works in C++. cv2.denoise_TVL1(img,dst,0.01,1). dst is zeros. Please help!

edit

that's a bug in the wrapping code, please raise an issue on the bugtracker

it should be OutputArray resulthere: https://github.com/opencv/opencv/blob...

(and the python version should return the result, not take it as a reference. (no need to preallocate it))

((unfortunately, impossible to fix before opencv4.0 , due to ABI requirements))
