摘要
为解决传统方法中由注意力曲线等长分段导致的精确率偏低的问题,提出了基于图像质量曲线提取关键视频段的方法,从各段内选取注意力值最高的帧作为关键帧。针对本地数据库进行视频关键帧提取,精确率为52.94%,F 值为62.77%,分别比Muhammad的方法提高了5.23%和2.65%。
Abstract
In order to solve the problem of low accuracy rate caused by the equal length segmentation of the attention curve in the traditional methods, a scheme is proposed, in which the key video segments are extracted based on the image quality curve. The frame with the highest attention value is selected from each segment as the key frame. On the local database, the precision and F-measure are 52.94% and 62.77%, 5.23% and 2.65% higher than those by the Muhammad method, respectively.
