压缩速度慢是吸引子图象编码技术实用化的最大障碍 ,因此 ,如何加速其编码过程 ,是当今吸引子图象编码的研究热点。本文提出一种快速吸引子编码的方法 ,它将分形维数作为衡量值域子块和定义域子块是否匹配的主要依据 ,有效避免了传统编码方法中子块匹配的耗时运算 ,同时采用气泡上浮法和二分法等快速排序和查找方法加速其编码过程。实验结果表明 ,该方案比传统 Jacquin方法快 5倍左右
Therefore, how to speed up the encoding process is the hotspot of the current attractor image coding. In this paper, a fast attractor coding method is proposed, which takes the fractal dimension as the main basis to measure whether the sub-block in the range sub-block and the sub-block in the definition domain match, which effectively avoids the time-consuming operation of the sub-block matching in the traditional coding method, Bubble float method and dichotomy rapid sorting and search methods to speed up the encoding process. Experimental results show that this scheme is about 5 times faster than the traditional Jacquin method
