| 摘 要： | 提出了一种基于HSV色彩模型的等高线提取方法.首先去除地形图中的黑色要素,然后选取原图等高线上一像素点色调值作为初值,按一定步长逐步扩大色调阈值,借助对应二值图连通区域数确定阈值区间.该算法无须人为指定聚类中心和类数,初始像素点的选取对提取结果不起决定作用.实验结果验证了算法的鲁棒性,并取得比较理想提取效果.

| Abstract: | An effective method based on HSV color model for extracting contour lines from color scanned topographical maps was proposed.Firstly the black elements were removed;the value of a pixel in contour line was regarded as the initial value;the scope of hue threshold was expanded in accord with definite step;the number of connectivity region was used to determine the threshold range. This algorithm does not need to artificially specify the centers and quantity of color clustering,and the choice of the initial pi... |
