| 摘 要： | 本文提出了一种新的地形图分色方法。首先去除背景像素,然后根据灰度梯度值提取主色像素,利用直方图模糊c-均值(FCM)聚类方法对主色像素进行颜色聚类,对去背景后的图像进行Canny算子的边缘检测。最后,利用加壳变换和障碍距离变换工具对符号周围的过渡像素进行聚类,从而实现黑棕兰绿四个分版图的提取。该方法效率较高,受图纸扫描质量的影响不大,分色效果较理想。

| Abstract: | An improved color segmentation algorithm was presented in the paper.The background pixels were removed firstly.The main color pixels of elements were extracted by gradient gray value and clustered by histogram fuzzy c-means(FCM) algorithm.The Canny edge detection for the image after removing background pixels was carried out.Based on adding-shell transformation and obstacle distance transformation the transition pixels on symbol brink were clustered,and the black,brown,blue and green element maps were extra... |
