And while it’s impossible for me to guess the criterion as to why you want to remove a contoured region from an image, the remainder of this blog post will demonstrate a toy example that you can use to remove contours from an image. This step could be very simple - or it also could be quite hard, it really depends on your application. The algorithm itself is very straightforward, the main step that you need to pay attention to and consider is Step 3, determining if a contour should be removed.
Step 4: Accumulate a mask of “bad” contours to be removed.Step 3: Determine if the contour is “bad” and should be removed according to some criterion.Step 2: Loop over contours individually.Step 1: Detect and find contours in your image.The basic algorithm for removing contours from an image goes something like this:
