The output of the Canny edge detector has lines of width only 1 pixel. How can I increase that width to 2-3 pixels by changing the parameters fed to cv2.Canny(), or changing some setting of cv2.Canny().

I don't prefer to use any post-processing method.

Good thing that OpenCV is open source. Check out the function for yourself to see if that kind of functionality is built-in.

Otherwise, check out dilation:
