说明：  《数字图像处理与机器视觉:Visual C++与Matlab实现》1 图像的点运算,图像的几何变换,空间域图像增强(&quot Digital image processing and machine vision: Visual C++ and Matlab to achieve&quot an image of the point operation, image geometric transformation, spatial domain image enhancement)

这几个程序是我用matlab做图像分割用到的，方法是四叉树分解，大家可以参考下(These programs do I use matlab image segmentation used, the method is the quadtree decomposition, we can refer to)

说明：  基于遗传算法的车间布局优化MATLAB源码 车间布局优化是将加工设备、物料输送设备、工作单元和通道走廊等布置物体合理地放置在一个有限的生产车间内的过程。车间布局优化模型是一个含有较为复杂约束的非线性连续优化模型，可以使用遗传算法进行优化。 (Layout based on genetic algorithms optimization MATLAB Optimization is the source plant processing equipment, material handling equipment, work unit and channel corridors reasonable layout objects placed in a limited course of the production workshop. Optimization Model is a workshop with more complex nonlinear continuous constrained optimization model, you can use the genetic algorithm optimization.)

关于演示旋转的一个应用程序，可以更好的理解体旋转的过程(The project is made by using GUIDE of Matlab 7.5.0 (R2007b) and user-defined classes. The project may be used on the seminars on mechanics in the technical educational establishments. Rigid body section of a course of mechanics is considered as required in most technical colleges and Universities. Sometimes it s difficult to imagine a rotation of a rigid body in the three-dimensional space. Especially, when an asymmetric top is in question. Rigid Body project may help students to see the rotations clearly as though they were in the real world. Author of Rigid Body project: Ferat Talat oglu )
