Abstract :
In this paper, a simple block-wise motion vector selection (BWMVS) strategy was incorporated into the motion estimation algorithm. The occlusion that severely damages the quality of the reconstructed video sequence in superresolution (SR) problem is effectively removed. The stability due to the BWMVS could be seen from the reconstruction results in comparison with the standard interpolation.
