Fast I-frames search algorithm for MPEG video streams

Existing methods for video indexing are not very efficient or accurate.This paper describes a fast I-frame search algorithm for MPEG (moving pictures experts group) video streams based on the structure and statistical characteristics of the MPEG video stream to achieve better I-frame locating.The algorithm also uses the Least Mean Squares(LMS) method to accelerate the frame search process.Simulations show that the algorithm has higher accuracy than existing methods and ensures quality with less calculations.The effect of this search algorithm is obvious.
