| Abstract: | Text area extraction from video caption has become an important tool for content-based video retrieval.Test object is frame data intercepted from video data.Segmentation methods of caption text that embedded in the color single-frame video by grayed processing are discussed.In this paper,the algorithm of area detection is proposed to solve the above problems.Experimental results show that the proposed approach is very effective and reasonable in text area detection. |
