when i press 'c' to capture hand histogram ,the program returned and display "contours,hierarchy=cv2.findContours(contour_frame,cv2.RETR_TREE,cv2.CHAIN_APPROX_SIMPLE) ValueError: too many values to unpack."

Thank you.

Thank you.

funtion "cv2.findContours(contour_frame,cv2.RETR_TREE,cv2.CHAIN_APPROX_SIMPLE)" returns total 3 values, so you have to put 3 variables on the LHS of the assignment

just replace that line with...

_,contours,hierarchy=cv2.findContours(contour_frame,cv2.RETR_TREE,cv2.CHAIN_APPROX_SIMPLE)
