  1. In this paper, two important modifications in dct - based coding algorithm are suggested after making deep study on the generally used scheme of h. 263 coder. first, we find plenty of invalid computation in the transformation part of the h. 263 coder and an improved scheme based on the pre - transform decision to avoid invalid computation is proposed. second, in the motion estimation part of the coder, we find that normal search algorithms are not effective, which neglects different levels of motion in image sequences, and we suggest a new search algorithm which has variable search region based on the difference of motion level. combining the pre - transform decision scheme with variable search region method in motion estimation, a global decision coding scheme is provided, which greatly increases the coding speed of h. 263 coder

    本文對h . 263編碼演算法的現有實現方法作了深入的分析,首先發現變換部分存在大量效運算,提出了在變換前判決的前變換判決的編碼方案,以壓縮效的變換運算;其發現運動估計部分由於忽略了圖像場景的分級運動而存在一定的效搜索運算,提出了基於分級運動的可變搜索域法來壓縮效的搜索運算;最後將前變換判決方案與運動估計的可變搜索域法有機地結合在一起,提出了全局判決編碼方案,從而比較全面地改進了現有實現方法,而能大幅地提高編碼器的編碼
