WebClosing Closing is reverse of Opening, Dilation followed by Erosion. It is useful in closing small holes inside the foreground objects, or small black points on the object. closing = cv2.morphologyEx (img, cv2.MORPH_CLOSE, kernel) Result: 5. Morphological Gradient It is the difference between dilation and erosion of an image.
