A transition pixel based detection and localization algorithm was proposed for the artificial texts in the video frame.The transition map was generated by extracting transition pixels in both horizontal and vertical directions.The transition pixels in the background were suppressed by block filtering, and candidate text regions were obtained by intensity based region growing.Finally, the candidate text regions were verified by improved local binary pattern (LBP).Experiment results have shown that, compared with Kim's work, the proposed approach can achieve more accurate text detection and localization.
