摘要
对比分析联合多视点视频编码中的全搜索算法和TZSearch(TZS)快速算法,描述TZS算法的原理及搜索过程并对其进行分析,并根据实验统计结果设置了使搜索提前终止的阈值.实验表明,在编码比特率轻微增加和峰值信噪比略微下降的条件下,设置了阈值的TZS算法比原有的联合多视点视频编码中的TZS算法在编码时间上大幅减少.对于运动比较平缓的序列适合采用阈值为2的TZS2算法,而对于运动比较剧烈的序列适合采用阈值为3的TZS3算法.
Comparative Analysis of full search algorithm and TZSearch（TZS） fast algorithm in joint multiview video coding,the principle and search process of TZS algorithm was described and analyzed.According to the experimental results,some threshold for early termination search was set.Experimental results show that under the conditions of a slight increase in the encoding bit rate and a slight decrease in the peak signal to noise ratio,TZS algorithm which is setted threshold has significant reduction in encoding time compared to the original TZS algorithm in the joint multiview video coding.For the sequence of gentle exercise are suitable for using the TZS2 algorithm with threshold value of 2,and for the sequence of more intense exercise are suitable for using the TZS3 algorithm with threshold value of 3.
