Hey python friends.
Sorry for the long code. Am doing a pong hand tracking for a project and need a full screen, the full screen works but i have an error with
img = cv2.addWeighted(img, 0.2, imgBackground, 0.8, 0)
Regarding the background overlay the error is:
File "D:\Stage\Hand gesture\Pong - HT - TekAngel\pong.py", line 91, in start_pong
img = cv2.addWeighted(img, 0.2, imgBackground, 0.8, 0)
cv2.error: OpenCV(4.5.5) D:\a\opencv-python\opencv-python\opencv\modules\core\src\arithm.cpp:650: error: (-209:Sizes of input arguments do not match) The operation is neither 'array op array' (where arrays have the same size and the same number of channels), nor 'array op scalar', nor 'scalar op array' in function 'cv::arithm_op
