一个混沌信号产生器MATLAB源代码。主要用于产生混沌信号序列。()

说明：  这里还有一个matlab和VC混合编程的，希望对学习matlab的人有帮助(Here is a matlab and VC programming mix, and want to help people to learn matlab)

分水岭分割的实现，主要分四个部分：1，模拟浸水过程；2，模拟降水过程；3，过度分割问题；4，标记分水岭分割算法(The realization of watershed segmentation is mainly divided into four parts: 1. 2. Simulated precipitation process; 3. Excessive segmentation; 4. Marking watershed segmentation algorithm)

里面包含两个程序，利用这两个程序你实现对于其他程序的处理。非常实用(Which contains two procedures, the use of these two procedures you implement other programs for processing. Very practical)
