The popularity of level sets for segmentation is mainly based on the sound and convenient treatment of regions and their boundaries. Unfortunately, this convenience is so far not known from level set methods when applied to images with more than two regions. This communication introduces a comparatively simple way how to extend active contours to multiple regions keeping the familiar quality of the two-phase case. We further suggest a strategy to determine the optimum number of regions as well as initializations for the contours.
水平集用于分割的流行主要基于对区域及其边界合理且便捷的处理。不幸的是，当应用于具有两个以上区域的图像时，目前还未发现水平集方法有这样的便利性。本文介绍了一种相对简单的方法，即如何将活动轮廓扩展到多个区域，同时保持两相情况下熟悉的特性。我们还提出了一种确定区域最佳数量以及轮廓初始化的策略。
