摘要
在电子稳像中提出一种中心扩展搜索算法,在改进全局搜索法的基础上结合最小中心偏置特性,根据视频偏移大小,调整搜索范围,具有全局搜索策略精度的同时,提高了搜索速度。
A center-expanded search algorithm was proposed for the electronic image stabilization .Based on improving the global search method and combing the minimum center offset characteristic as well as according to the video offsets , the proposed algorithm can adjust search scope and has precision same as the global search strategy.It can improve search speed .
