Python Opencv Contours Stack Overflow

Python Opencv Contours Stack Overflow Using the thresholded image, we detect contours using both the full and simple approximations. this gets stored in two lists, contours1 and contours2. the contours themselves get stored as a list of numpy arrays. Work with connected components. for each pixel column (or whichever you desire), find the first and last pixel in the contour. you can do that with some numpy functions. if the shapes are filled, you can just do a columnwise sum, hence counting, which is equal to the “thickness” in that column.
