应用于面状地理实体聚类分析的线段链形状相似性准则

A Criterion of Shape Similarity Between Line Segments for Clustering Analysis of Geographical Area Entities

    摘要
  • 摘要: 提出了一种满足旋转与平移不变性的线段链形状相似性评价方法。该方法计算简便,适用于面状地理实体聚类分析,并给出了该评价方法的实现算法,分析了参数对评价方法可能产生的影响及影响程度

     

    Abstract: A criterion of shape similarity between line segments is presented, which meets rotating invariance and translation invariance. The method is ease in calculation and fit for clustering analysis of geographical area entities. An algorithm of calculating shape similarity between line segments is put forward. The influence of different parameters on criterion results is analyzed.
