摘　　要：应用基于水平集的多相活动轮廓模型对云图进行多类别分割,云图被自动分割成几个区域,不同区域就对应着不同的云顶高度,区域分割结果可以使对一幅云图中不同高度云的分布以及哪种类型的云占主体有总体的认识和了解,从而对天气系统的分析具有一定的辅助参考作用。The paper employs the multi-phase active contour model based on level set for multiple classes cloud segmentation in meteorological satellite cloud imagery. Image is automatically decomposed into a set of coherent regions, which corresponding to different levels of cloud top height. The region-based segmentation is found to be helpful to understand the distribution of cloud at different levels in image as a whole, and moreover, could give reference to the analysis for weather system to some extent.
