Research on Edge Detection Algorithm for Caption Extraction from Video Frames
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.This paper proposes an algorithm of edge detection to extract caption text that embedded in the video frame by grayed processing.Experimental results have shown that the proposed approach is very effective in text area detection.
