In the news video, As a high-level semantic features, video text play a crucial role for the semantics understanding, video analysis, quick video clips retrieval of news video. We propose a new video character extraction method that is gray-based. It makes full use of gray information of the video image and the news video text features to detect the video frame which contain text information, and uses mathematical statistical method to find the location where text appears, then do the binary processing of the candidate region image, at last uses OCR software package to recognize the text. This article also finish a simple news video retrieval system, and text extraction algorithm is applied to the system. Experiment results on Chinese CCTV news video show the encouraging performance of the proposed algorithm.
