re: Finger Detection and Tracking using OpenCV and Python VIEW POST


Got this error after I pressed 'z' key:

Traceback (most recent call last):
File "FingerDetection.py", line 186, in
File "FingerDetection.py", line 171, in main
manage_image_opr(frame, hand_hist)
File "FingerDetection.py", line 136, in manage_image_opr
contour_list = contours(hist_mask_image)
File "FingerDetection.py", line 23, in contours
_, cont, hierarchy = cv2.findContours(thresh, cv2.RETR_TREE, cv2.CHAIN_APPROX_SIMPLE)
ValueError: not enough values to unpack (expected 3, got 2)

Do you have any idea?


@tungts1101 I will suggest you use opencv-python version 3.4.*. You are facing this issue because you are using some higher version of opencv-python.

You can download the correct dependencies using requirement.txt file present in the repository.

Hint: Use command sudo pip install -r requirement.txt


That's work. But I think there's still something need to be done in order to eliminate noise in background.

Yes, that's an issue. You can take that up if you want.
