A Novel Video Text Detection and Localization Approach

Abstract

Text detection and localization in videos are often used for video information indexing and retrieval, as text can retrieve the semantic information of videos. In this paper, we propose a novel approach to detect and localize texts by means of integrating the multiple video frames and multiple video frame motion features. For text detection, first, the motion feature detection is employed to fulfill the multiple frame verification. Second, the synthesized motion feature image, which is produced by motion vector on consecutive frames, is used to detect the text region under a synthesized image, which is produced by multiframe integration. Third, corner points are employed to locate the candidate text pixels position and a region growing algorithm is developed to connect these pixels into text blocks. In text localization, we use the corner points to accurately locate the text region. Experimental results show satisfying performance of the proposed algorithm.KeywordsText detectiontext localizationmultiframe integrationmultiframe verification
