【摘要】 介绍了适合H 2 6 3的一种改进算法。改进的新三步法(improvedNTSS) ,基于NTSS的改进方案 ,结合H 2 6 3(+)的高级选项使用时可以大大减少计算量。采用全搜索算法计算量最大 ,各种快速算法都是以限制搜索步骤或点数来换取计算量的大大减少 ,同时保证了性能的降低最小。无论运动图像剧烈与否 ,该方案都提出了克服的方法。实际测试表明 :改进的这种方法性能上几乎达到了全搜索法 (FS)的结果 ,而时间上只有FS的 5 %左右更多还原

【Abstract】 This paper discusses an improved algorithm for H 263(+)-INTSS This NTSS based scheme may save much time by using the advanced selected topics of H 263(+) FS uses the most time in all algorithms All kinds of fast algorithms must limit the searching steps and the searching points to save much more time At the some time,we ensure that the decrease of quality is the least No matter how quickly the image moves,this algorithm can overcome it In fact, the test suggests that the algorithm has the same quality as FS, but it takes only 5% of FS time更多还原
