an error or imperfection when the frame don't have any feature point #4

Closed zhongtao93 closed 5 years ago

zhongtao93 commented 5 years ago

In mesh_flow.ipynb , an error occur when one frame has no feature point: # calculate optical flow p1, st, err = cv2.calcOpticalFlowPyrLK(old_gray, frame_gray, p0, None, **lk_params)

This problem occur definitely when a video has a blank or black frame, can you provide a more rebust code for this solution.

Thank you very much!
