Webb1 nov. 2015 · As we know, optical flow is the approximated motion vector at each pixel location, which can reflect the relative distances of moving objects. Therefore, it is important and useful in video surveillance and abnormal events detection. Other methods based on the histogram of optical flow were described in [19–21].
