基于FAST角点检测的快速字幕定位方法

FAST Subtitle Localization Method Based on FAST Corner Detection

字幕信息在视频和图像的检索和分析中起着重要作用。文章基于字幕区域丰富密集角点与边缘特点,通过FAST角点检测算法,进行水平积分投影与连通域分析,对行列进行定位,通过使用FAST角点检测算法与快速字幕定位的方法,启发性规则验证从而确定字幕的区域未知,通过测试实验结果印证了此类方法的有效性。

Subtitle information plays an important role in video and image retrieval and analysis.A FAST subtitle location method based on the FAST feature From Accelerated Segment Test(Accelerated Segment Test)is proposed.According to the rich and dense corner and edge characteristics of the subtitle area,this method USES FAST corner detection algorithm to obtain the corner information,and performs line and line positioning through horizontal integral projection and connected domain analysis,and finally verifies by heuristic rules to determine the subtitle area.Experimental results show that the method is effective.
