Can we use «MatOfPoint2f prevPts» an array of all the points MatOfPoint2f[] in method Video.calcOpticalFlowPyrLK as an input parameter, like in OpenCV for Windows?
For Android I only can do the following:
Video.calcOpticalFlowPyrLK(Cadr_Prev,Cadr_Current,
Point_PrevPts[iindex],
Point_CurrentPts[iindex],
_bstatus[iindex],
_trackError[iindex]);
P.S. I run in cycle the function calcOpticalFlowPyrLK for each point and it affects on productivity.
