摘　　要：本文基于分形插值 ,提出了一种新的序列断层间图像轮廓的计算方法 ,该算法具有分形几何的一般特点 ,可很好地表示轮廓的不规则性 ,从而可准确地表现序列断层间图像轮廓的形状 .文中结合医学图像给出了算法实现 ,结果表明该算法具有较高的保形性 ,且运算量与存储量都非常小 .A novel planer contours reconstruction algorithm based on fractal interpolation is presented.With the intrinsic property of fractal geometry,the algorithm can be used for describing irregularity of planer contours and representing the shape between two planer contours. In the paper,the new interpolation method is achieved and applied to medical images experiment.The study results show that the proposed approach can preserve the shape of the planer contours accurately,and the amount of computation and storage is very little.
