Motion estimation using block overlap minimization
Michael Santoro, Ghassan AlRegib, Y. Altunbasak · 2012
This paper presents a block-overlap-based method for handling the ill-posed nature of motion estimation. The proposed method uses the volume of motion-compensated block overlap as an additional term in minimizing the overall energy. By reducing the amount of block overlap, the proposed method results in a significant improvement in the quality of the motion field. Experimental results show that the proposed method outperforms several existing methods in the literature in terms of motion vector (MV) and interpolation quality. In terms of interpolation quality, our algorithm outperforms all other block-based methods as well as several complex optical flow methods. In addition, it is the fastest non-GPU implementation at the time of this writing.
