How to crop the image as wide as possible? I want to be able to crop any image with the smallest bounding box possible.

I have a binarized image by Otsu Threshold. I'm new in C++ and Opencv. I try this, but don't work.

If yes, when i try shows an erro in oparetor "norm" and yours arguments.

I wuld replace this part: for (size_t cC = 0; cC < contours.size(); ++cC) for (size_t cP = 0; cP < cont
