Caption location, tracking and enhancement in digital video

Abstract

Novel algorithms for locating, tracking and enhancing captions in digital videos are proposed. First, the candidate caption regions in video frames are located using colour edge information. Second, the candidate regions are tracked according to the temporal redundancy in video seqttettces. Tkird, the detected captioRs ace e~kat~ced by multiframe integration. Experimental results show that the detection rate is high and the enhancement is notable. Index Terms caption detection; edge information;.temporal information
