  • Abstract
    A new motion vector recovery algorithm based on optical flow is proposed. Optical flow fields are very similar to the true motion and can be used to recover three-dimensional motion information. Experimental results on test video sequences produced a higher peak signal-to-noise ratio value than that of conventional methods based on the block matching algorithm
