An Efficient Bit Allocation Scheme Considering Scene Change
초록
A rate control strategy in the MPEG is critical to the quality of the reconstructed image sequence. In this paper, were propose a rate control algorithm which can improve the coding performance for a given bit constraint. The proposed algorithm use the distortion-rate curve for the fine adjustment of the quantization scaling factor of each region. This algorithm can also handle the problem due to scene change effectively. It can be easily applicable to existing MPEG coders. Simulation results show that the performance for the algorithm is better than the rate control algorithm in the MPEG-2 TM5.
