  • Abstract
    We examine the problem of estimating a reverse motion vector field from a given forward motion vector field and its motion-compensated residual. This problem has practical importance when providing reverse-play functionality in compressed video environments, where video data is stored, processed, and transported in compressed form. We present a family of algorithms that trade off motion vector accuracy for computational efficiency. Experimental results demonstrate the performance of these algorithms
