So it seems that there is a problem when cv2.cvtColor() is called in emotion-program.py, which is considered odd since it is a standard function in OpenCV

What version of OpenCV are you running? I suspect that since your path says "opencv-2.4.8", you are probably running an old version of OpenCV. This program was tested with OpenCV 3 or above, try installing OpenCV 3.0 or above and tell us if you still receive the same issue.

I already tried installing OpenCV 3.0, and the issue still persists. I have attached an image below for your reference

Edit: I looked up the error "OpenCV Error: Assertion failed (scn == 3 || scn == 4) in cvtColor", and it looks like it has something to do with the code(?).

It is possible that the problem is variable "frame_f" could be null.

Right before line 54 (prev_gray = cv2.cvtColor(frame_f, cv2.COLOR_BGR2GRAY)), can you insert this code and tell me what prints out:

cv2.imshow("Test frame", frame_f) cv2.waitKey(0)

If frame_f is not null, then a picture show pop up.
