2014-02-23 23:43:16 -0600 | asked a question | How to create my own filter to detect a pixel is a local maximum? Hello, I am interested into doing this from the Python cv2 wrapper of OpenCV. I'd like to test each pixel of a gray image to see if it has a value >= to the value of its 9 neighbors. The output should be a binary mask, preferably of the same size than the input image. Thanks, F. |
