Hi,Fready,
Title: 
	DOF result have a large deviation.
Purpose:
	After many tests, we find the results obtained by our 7.3SDK DOF demo have a large error.
	while tracking results of Farneback in OpenCV are basically consistent with our LK optical flow. 
	We hope to get similar results to our LK optical flow based on DOF demo code.
Reference:
	1.Our demo program and result could be seen by attachment: DOF.7z, Result_Image.7z.
	2.Mark methods:
	(1) Take corner points;
    (2) OpenCV code could be seen by attachment: Tda4vsopencv_opticalflowfarneback.7z (OpenCV version: opencv_python-3.3.0.9-cp36-cp36m-win32, Python: Python-3.6.2), the video will be sent to you Wechat;
    (3) DOF marks (u, V) of corresponding corner points in bin files, and Matlab tracing points is enough;
