ZHU Shi-ping ZHANG Lin. Video coding system based on fractal and H.264[J]. Editorial Office of Optics and Precision Engineering, 2013,21(3): 774-781 DOI: 10.3788/OPE.20132103.0774.
On the basis of the fractal encoding technology with a higher speed
a new H.264PP frame prediction method and a corresponding fast coding system were proposed to decrease the video compression coding time and bite rate . Firstly
the main ideas of intra-/inter-prediction in H.264 and their advantages and disadvantages in P frame encoding were analyzed. Then
the new video compression method based on the fractal video compression and its characteristics were discussed. Furthermore
by combining the advantages of new standard H.264 with fractal video compression method
the P frame in H.264 was predicted by proposed method. Finally
the fractal coefficient coding and residual coding generated from fractal prediction encoding were given. Experimental results show that the proposed coding system has reduced the bite rate and the encoding time to 65% and 19% respectively those of the H.264 reference software JM15.1
while the Peak Signal Noise Ratio(PSNR) can be ignored (average reduce 0.09 dB). These results can satisfy the requirements of variable motion video sequences and can improve the overall performance of the H.264 video coding system.
