- The jacquin algorithm of fractal image coding is modified according to the modern optimization theory . the aim is to reduce the coding time
本文采用现代优化算法对分形图像压缩编码的简库恩算法进行改进，以期达到在不降低分形编码峰值信噪比和压缩比的前提下使编码时间减少的目的。 - At first the problem of the matching search of domain and range in the jacquin algorithm of fractal image coding has been analyzed and the result of it belonging to the np _ hard has been found
首先经过分析发现简库恩算法中的定义域、值域匹配搜索问题属于组合优化问题中的np ? hard ，并把组合优化方法应用于分形图像压缩编码的搜索过程。 - As a result , the contractive mappings can be achieved in order to make the fractal image compression automatically realized . it is tested that the approach we proposed is simple but available all through the experiment
与jacquin的方法相比，由于引入了区域形状编码，增加了编码的复杂度，但在解码图象质量相近的情况下，提高了压缩比。 - Then , in the second chapter , we generalize the mathematical principle of fractal image compression . in the third chapter , we introduce jacquin ' s fractal image compres - sion method and fisher ' s self - adapted quadtree image compression method
