Abstract :
The accuracy of optical flow estimation is much worth on the occluded and appeared objects. In this paper, we describe an extrapolation method for improving the accuracy of optical flow estimation based on the characteristics of constraint lines in the velocity space and the extraction of the occluded/appeared regions using cluster analysis
