In the H.264/AVC standard,the de-blocking filtering is an effective way to improve the image quality and compression efficiency,but it contains a very high computational complexity.In the whole filtering process,the computation of the boundary strength(Bs) is the largest part,which is almost 90%.A new algorithm for H.264 de-blocking filter based on quick decision of Bs is proposed after analyzing the theory of Bs decision.The experimental data show that the FF algorithm is able to maintain the quality of codec video images,and compared with standard algorithm in JM,it can reduce nearly 50% of Bs decision time and nearly 20% of filtering time.Then,compared with any other improved filtering algorithms,it has its own advantages.Therefore,the FF algorithm can effectively decrease the computational complexity of de-blocking filter and can promote the realization of real-time transmission of video sequences.
