| 摘 要： | 该文在分析地图图像特点的基础上,提出了一种适于地图分色的像素边缘梯度算法,其思想是将像素梯度的概念延伸到像素边缘的梯度。进而,利用数学形态学的变换原理,探讨了对分色结果进行后处理以及细化的具体过程。棕版图的实验结果证明,用此算法提取线状信息定位精度高,连续性好,处理速度快,并可以很好地解决粘连及背景噪声等问题,细化后的结果能够满足需要。

| Abstract: | In this paper,a kind of pixel's edge-gradient algorithm applied to the segmentation of color map is present-ed on the basis of analyzing the characteristics of maps,in which the concept of a pixel's gradient is extended to that of the pixel's four edge-gradients,further,after-processing,as well as thinning is also processed with mathematical mor-phology.Experiments with brown edition prove that the positioning of lines and running speed of this algorithm are sat-isfied and the problems of conglutination and noise of background can be well solved.The result can meet general re-quirements. |
