摘要
传统的方法是用统计特性来分析和描述地形特征,对于具有相似统计特征的区域则往往失去效用。提供一种基于地形结构纹理特征的分形描述方法,描述的对象是多尺度结构特征,从地形的形成机理特性出发,符合人类从粗至细的视觉特性,体现了在不同分辨率下逐步求精的过程。
The traditional method via statistical characteristics is usually used to describe terrain features. However, it will fail to discriminate some regions with similar statistics. A fractal method based on texture and structure of terrain is presented. The object described by this method is multi\|scale structural feature. According to the characteristic of human vision and starting with inherent mechanism of terrain, the method embodies the procedure of gradual analysis under multi\|resolutions.
