Paper Abstract

The effect of image stabilization on the performance of the MPEG-2 video coding algorithm is investigated. It is shown that image stabilization prior to MPEG-2 coding of an unsteady image sequence does increase the quality of the compressed video considerably. The quality improvement is explained by fact that an actual zero motion vector is favored over a zero differential motion vector in the MPEG-2 video coding scheme. The bits saved in coding the motion information in P frames are then utilized in the coding of the DCT data in I frames. The temporal prediction of the macroblocks in P and B frames are also improved because of the increased quality of the compressed I frames and because an image stabilization algorithm can compensate for displacement with better than 1/2 pixel accuracy.
