| 摘 要： | 根据维吾尔文字独有的基线特性,提出了一种新的视频维吾尔文字幕帧提取方法,首先进行维吾尔文字幕帧的读取,然后根据相邻帧之间的像素帧间差异和区域像素统计对视频段作初步镜头关键帧的检测,之后对检测到的镜头关键帧作区域处理,检测视频帧中是否具有基线特性,再根据基线设置阈值,最后提取出代表视频语义的主要视频帧。实验证明:该提取方法简洁有效,其字幕帧提取率平均可达到85%以上。

| Abstract: | A new method for extraction of subtitle frames in Uighur video based on baseline is proposed.Firstly,according to pixel frame difference between frames and region pixel statistics,test shot key frames that detected from the previous step,then process regionly on shot key frame to test if video frame has baseline feature,then set threshold according to baseline.Finally extract main video frame which represents video meaning.The experimental results demonstrate that the method is simple and effective,and the subtitle frame extraction rate can reach more than 85 % on average. |
