基于分色和一种新的去噪算法的地图自动输入技术

Auto-map Reading by Color Segmentations and New Filtering Algorithm

介绍一种利用图象处理方法对彩色地图进行识别，从而自动建立地图数据库的方法。首先用分色法对地图中的道路进行识别和抽取，再利用一种新的去噪算法进行去噪，然后进行城市识别和矢量化，得到地图数据库。最后给出了实验结果。

A method of recognizing the color map and building the map database by image processing is given. First recognize and extractthe road by color, then filter the noise using a new algorithm, build the map database at last. The result of experiment is given at the end.
