摘　　要：鉴于自然物体图象具有分形特性，提出一种基于分形几何原理的放大图象的处理方法，它通过提取图象的分形参数，采用了随机中点位移法进行插值。This paper deals with an approach for enlarging an image based on fractal geometry model. It extracts the fractal factor from a picture first, and then the random middle point offsetting is used to add more points for interpolation. The case study shows that the enlarged image quality using this new approach is very good.

关 键 词：图象放大 图象处理 分形几何 放大算法
