【摘要】 提出了一种基于自适应四叉树分形图像编码的并行算法。实验结果表明,在信噪比不变,压缩比微弱减小的情况下,并行算法的编码速度显著提高,为原编码速度的近4倍。更多还原

【Abstract】 A parallel algorithm for the adaptive quadtree fractal image coding was presented.Experimental results show that,with the same PSNR and a little loss of the compression ratio,the proposed parallel algorithm improves the encoding speed largely,which is about four times of the original coding’s.更多还原
