结合颜色特征和结构特征的彩色地图分层算法

Automatic Segmentation of Color Map Images Based on Color and Structure Features

在分析了彩色地图图像分层的特点、难点的基础上 ,提出直接基于RGB颜色模型的分层算法 同时针对分层得到的单版图存在信息丢失、难以恢复的问题 ,提出先对所有目标细化 ,然后再分层的新思路 ,并结合结构特征恢复丢失信息、改善分层效果 最后 。

An algorithm directly based on RGB color model to enhance the quality and performance of color map segmentation is proposed The problem of information losing in segmentation is solved by carrying out segmentation after thinning of all objects and making use of structure features to improve segmentation results Experiments on many real maps illustrate the effectiveness of the above mentioned approach
