Terrain Roughness Measure Based on Mathematical Morphological Filter

研究新的地形粗糙度定义与算法 ;基于数学形态滤波方法 ,定义了一种新的地形粗糙度 ;讨论了新粗糙度的性质与计算方法 ;通过对典型地形计算结果的分析 ,表明该新粗糙度定义是可行的 ,具有直观形象。

A new method to measure the terrain roughness is given, which is based on mathematical morphological filter. Compared with the current ones, measurement by this new method is vivid and audio-visual, and simple to calculate. The simulating test results are also given.
