ValueError: tile cannot extend outside image #1

When the face goes to the image limits it fails:

Yeah because code tries to draw a rectangle around the face. You can try to cancel it.

I have deleted the code for drawing, but I have de same error:

I think you can view the outputs of face detection model which is rectangle pixel values of the face. You can add new conditions like that if the returned boundaries are out of the camera regions, don't do anything. Also I added extra pixels around the face because classification model can not classify the face properly due to detected face does not cover the all face properly. You can focus this point. If face is not in the middle of the camera region, added extra pixels cause this issue.

If this will not work, I will view my codes in my free time, but also I have realized that this issue before I uploaded my codes into GitHub.

I check the limits before assign current_face and now it works fine:

        if startX - extra_pixel < 0 or startY - extra_pixel < 0:
            break

Thanks a lot for your code!

You're welcome :)
