摘要
对彩色扫描地图图像的色彩误差进行了分析 ,运用特征向量匹配法对地图上黑版要素进行分层 ,然后对地图的色彩空间进行转换 ,并提出了基于二维直方图模糊约束的模糊C 均值 (FCM)聚类方法 ,较好地解决了地图的自动分色问题 .该方法已编程实现 。
Color inaccuracy of a scanned color map is analyzed. To solve this problem, eigenvector line fitting algorithm is used for black element segmentation. With transformation of the color space, a new effective fuzzy clustering based on fuzzy restraint two dimension histogram is presented for color elements segmentation. The algorithm has been experimentally verified to be robust and accurate.
