将视频序列通过关键帧提取的方式转换成静态图像,然后利用图像处理技术进行分析是视频处理的一种有效方法。首先讨论了近年来基于压缩域的关键帧提取技术,然后分析和讨论了针对敏感视频识别应用的关键帧提取方法,并给出了一种快速有效的关键帧提取方案。
The approach of retrieve key frames from video and then process them is an efficient way to process video data.Reviewed the research results of extracting key frames based on compressed domain in recently years,and made analysis and discussion to retrieve key frames for applications to identify objectionable video.Proposed a fast and efficient scheme for this goal at the end.
