| 摘 要： | 通过对搜寻码本设置门限的方法来调节对比度因子,提出了基于对比度因子调节的快速分形解码算法.实验结果表明,该算法获得了较基本分形算法质量高的第一次迭代后图像,在图像质量降质较小的情况下比基本分形解码明显地加快了收敛速度,从而可较好地满足需要超高速图像解码的应用场合(如实时视频传输).

| Abstract: | A new algorithm was proposed for fast fractal image decoding based on the contrast factors adjusted through setting some thresholds for the codebook.The experiment results showed that the algorithm could gain a higher quality of decoding image after the first iteration decoding than the baseline fractal decoding,accelerate obviously the convergence compared to the baseline fractal decoding with a less degradation of the decoded image,and then was preferably content to the case of super-fast image decoding applications(e.g.,real-time video transmission). |
