Opencv / python: draw image via webcam stream

Hi everyone, I am trying to make a game with my webcam where I need some objects to fall on the screen while I was streaming a video with my webcam (this stream was my background).

Question: How do I draw an image over this background? I know how to capture each frame and that I need to draw the image over the frames, but using what?

  • For this I am using python and opencv and the cv2 module .
  • I already searched and I found that you can use regions. Interest in this, but I am using cv2, and they say that using numpy arrays which is much easier .. but I don’t understand how to do that ..

Can anyone give me some advice or examples on how to do this?

Thanks in advance!

Here's an example. It also shows you how to overlay transparent images. You can use the built-in drawing functions . There's a neat little trick for drawing transparent shapes too.
