CAPTION SEGMENTATION AND RECOGNITION METHOD IN NEWS VIDEO

摘要

The present invention relates to a method of automatically extracting and recognizing subtitles from a video image, and conventionally, a simple index retrieval method does not express various meanings of an image and thus does not satisfy a search requirement of various users.;Therefore, when the video input image (contrast value image) of one frame comes in, the present invention extracts a place where there is a sign of a news subtitle from the whole image, and examines whether the extracted candidate region continues in successive frames. Extract the subtitles, perform large-scale segmentation and verification to verify that the candidate subtitles of the extracted subtitles are true subtitles, and perform the extracted subtitle recognition step using the recognition means for the individual character regions obtained in the segmentation process. As a result, news video subtitle extraction and recognition is possible.
