进化策略在最佳邻域匹配差错补偿中的应用

Evolutionary strategy with its application to best-neighbourhood matching error concealment algorithm

文中改进了BNM的搜索机制 ,提出结合进化策略 (ES)的ES BNM的差错补偿算法 ,比较实验证明 ,该算法在结果接近BNM算法的同时 ,大大减少了计算时间 ,提高了计算效率。ES BNM算法也再一次证明了进化算法是一种高效的优化搜索方法。

This paper proposes an improved version of the BNM method by combing Evolutionary Strategy(ES)into the searching procedures The experiments and comparisons to the basic BNM show that ES BNM algorithm can obtain similar error concealment results in much shorter time ES BNM can be viewed as a new successful application of ES that demonstrates the powerful searching ability of ES
