Hello i read this article http://queue.acm.org/detail.cfm?id=2206309
and saw optical flow with OpenCV should be 1.6 times faster on Tegra3 with
So i tried an easy example and measured the time it takes to call
goodFeaturesToTrack() and calcOpticalFlowPyrLK()
The result was, with Tegra3 lib (arm/neon) and OpenCV 2.4.2 i'm only 12%
Can anybody interpret my result? Why is the gain so small?
