Suggestion about take_pic.py

[qimingyudaowenti]

Hi, TreB1eN! When I run take_pic.py to crop face, I find two little problems:

1. The script isn't sensitive enough to my press (especially when I press q for quitting).
2. The text in crop area will be saved.

I think the code could be better like:

while cap.isOpened():
    isSuccess, frame = cap.read()

    press_key = cv2.waitKey(1) & 0xFF
    if press_key == ord('t'):
        ...
    elif press_key == ord('q'):
        break

    if isSuccess:
        frame_text = cv2.putText(...)
        ...

cap.release()
