Hello community,
I'm using opencv library to get a flow of movement that triggers a camera.capture() function. I need a filmename.jpg, at the instant of movement.
The test code, i'm using /opencv/samples/lk_track.py. But i got this error.
Lucas-Kanade tracker
====================
Lucas-Kanade sparse optical flow demo. Uses goodFeaturesToTrack
for track initialization and back-tracking for match verification
between frames.
Usage
