Abstract :
High accuracy prediction for pixel information of current frame can be achieved by means of intra prediction of H.264 video encode, the image data can be transmitted with minimal residual data. The feasibility of fast edge detection for current frame using intra prediction data during H.264 encoding process has been studied, and edge detection by intra prediction data has been actualized. Finally advantages and disadvantages of the algorithm, and the aspect needs to be improved has figured out.
