具有可逆性与周期性的Arnold置乱变换，目的是实现对图像的置乱，用于图像加密中(The realization of image scrambling, used in image encryption)

这个文件用PCD算法解决压缩感知（构造一个冗余字典用于图像的修复）(Using PCD algorithm to solve compressed sensing (constructing a redundant dictionary for image restoration).)

提取并显示鼠标所在图像点的颜色，C++精选学习源码，很好的参考资料。(To extract and display the image color, select learning C++ source code, a good reference.)

灰度图像直方图的计算，超级好用的啊，可以通过它获得图像的分形维数等等，内存小，功能大(Gray image histogram calculation, super nice ah, you can get through it the fractal dimension of the image, and so on, the memory is small, functional large)

利用matlab实现图像的边界检测。包括sobels算子，prewitt算子，还包括图像的边界追踪(use matlab to detect the boundary of the image)

卡尔曼和Camshift结合的源代码，很不错的哦，大家可以一试。。(Camshift Kalman and the combination of source code, very nice Oh, we can try to do. .)

roewa算子，源代码，适用于SAR图像(Roewa operator Applies to SAR image)

找待选物体图像的长轴位置(find objects to be elected to the long axis image location)

说明：  基于角谱理论艾里光束的传播,该MATLAB程序，大体上模拟出了Airy光束的二维光强分布，并在此基础上利用角谱理论，编写出了其在二维平面内的传播，只需改变其中的参数就可以展示Airy光束的移动。在此基础上加上障碍物，可以得到Airy光束的自愈合特性等特殊性质(The matlab program, in general, simulates the two-dimensional light intensity distribution of Airy beam, and on this basis, using the angle spectrum theory, compiles its propagation in the two-dimensional plane, only changing the parameters can show the movement of Airy beam. On this basis, the self-healing properties of Airy beams can be obtained by adding obstacles)

主要包括3种去噪方法，Bayesian Least Squares，BM3d 和Non-local means (this attachment contains three classical denoising methods Bayesian Least Squares，BM3d and Non-local means )
