程序实现一个自适应阈值的算法，用以在不规则光照下从背景中提取出前景图像。-Procedures to achieve an adaptive threshold algorithm to extract the foreground from the background image in the irregular light.

比较流行的数字电子钟，完全基于软件实现的效果，不依赖任何位图资源，可以设置背景和前景色，通过本程序你还将学到更多有用的知识点。-The number of the more popular electronic clock, based solely on the effect of software does not rely on any bitmap resources that can set the background and foreground through this prog

by traditional level set based segmentation models. In this paper, we propose a new level set method integrating local and global intensity information adaptively to segment inhomogeneous images. The local image information is associated with the
