The Method of News Captions Extraction Based on Color Analysis

Li Qiong  
The extraction of video captions is an effective method for constructing the index of video information.The sticking point for the process of captions extraction is identification and location of the area with captions in image frames and affects efficiency of recognizing text.A method is used to divide the video into scenes by calculating time correlation between video frames according to the change of frame background.Then a novel method is presented to locate and extract the area with captions in video frames sequence based on chromatic analysis.The method makes up of the variance of the pixel with the same location in video frames to describe time inflexibility after dividing video into scenes.Finally,the experimental result shows that the method is valid.
