An Approach for Video-text Extraction based on Text Traversing Line and Stroke Connectivity

WANG Zhi-ming①,TIAN Po-huang② (①Huaihau Vocational and Technical College,Huaihua Hunan 418000,China;②Zhengzhou Information Science and Technology Institute,Zhengzhou Henan 450002,China)  
In the complicated background,conventional automatic video-text location methods can not robustly locate text.A novel video-text location method is proposed in this paper.It falls into two stages:in the first stage,an unsupervised paradigm based on wavelet is applied to obtain candidate text region;in the second stage,traversing line with its amplitude spectrum is introduced and applied to create boundary for each text line.Experiment indicates that this scheme can robustly locate the text of various colors,fonts,and sizes in the complicated background,and performs better than schemes in [5] and [7].
