说明：  基于MATLAB编程的菲涅耳离轴全息图的记录(Recording of Fresnel off-axis hologram)

说明：  图像重定向源代码，本文提出一种网格变形框架，允许显著特征进行均匀缩放，从而保证图像内容的完整性，将变形分布到不重要的区域。(The source code of optimal scale stretching image redirection is presented, and an effective image redirection algorithm is proposed to better guarantee the integrity of the image.)

副高五个指数的计算，可根据需要修改，数据需要提取，注意修改区域(the index of subtropical high)

用小波的模极大值法有效检测噪声图像的边缘(Detecting the edge of noisy image by modulus maximum method of wavelet transform)

利用raycasting实现三维重建,直接体绘制，老外写的(raycasting volume rendering C++ C# vs2008)

医疗图像分割，GUI，可视化,能够实现对医疗图像感兴趣区域分割，GUI显示，三维可视化(Medical image segmentation, GUI, visualization)

利用模糊C均值图像分割,此为matlab环境下的仿真代码.(Using fuzzy C-means image segmentation, this matlab code simulation environment.)

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)

说明：  使用MATLAB提取二值图像特征值，并对连通区域进行标记、分析与计算(MATLAB is used to extract the binary image feature values, and mark, analyze and calculate the connected area)

Cohen类时频方法采用不同的核函数来抑制交叉项，本质上是在模糊域对信号进行低通滤波，其中典型的方法有Choi-Williams 分布和Cone-shaped 分布等。(The Cohen time frequency method uses different kernel functions to suppress the cross term, which is essentially a low pass filter for the signal in the fuzzy domain. The typical methods are Choi-Williams distribution and Cone-shaped distribution.)
