| 摘 要： | 针对彩色地形图的自动分色问题，提出了一种新的模糊聚类算法。该方法首先对地图的色彩空间进行转换，使其支方图的峰谷特性更加明显，然后对模糊C—均值(FCM)聚类算法进行模糊约束，并把此算法扩展到2维空间，从而较好地解决了地图的自动分色问题。此算法已编程实现，效果比较理想。

Automatic Color Segmentation of Topographic Maps Based on Color Space Transformation and Fuzzy Restraint Clustering |
| |
| Abstract: | Aimed at the automatic color segmentation of topographic maps, a new effective fuzzy clustering algorithm is presented. The color space of the map image is transformed firstly and as a result the kurtosis of the histogram is more apparent. FCM algorithm is reformed by fuzzy restraint and applied in two dimensions space afterward. The question of automatic color segmentation of topographic maps is resolved at last. The algorithm has been implemented on computer and a good result has been obtainned. |
