Witryna9 paź 2024 · Finally, let's apply Canny edge detection to a video in real-time! We'll display the video being processed (each frame as it's done) using cv2.imshow () which displays a window with the frame we'd like to display. Though, we'll also save the video into an MP4 file that can later be inspected and shared.
