Imageprocessing
包括图像分析的四部分代码:matlab扩散和高斯函数,线性扩散,线性复扩散,非线性扩散。(It contains four parts:
[1]MATLAB function:diffusion.m gauss.m
[2]Linear diffusion
Applying linear diffusion to images creating linear scale-space.
MATLAB code: demo_lin.m
Image: haifa1.bmp
[3]Linear complex diffusion
Applying linear complex diffusion creating Gaussian and Laplacian scale-spaces. MATLAB code: demo_cmplin.m
[4]Nonlinear diffusions:
Perona-Malik ["Anisotropic diffusion"]
Catte et al. regularization of P-M
Complex ramp-preserving diffusion
Nonlinear edge preserving diffusions.The classical Perona-Malik process: the value of the diffusion coefficient is reduced near edges estimated by the first derivative. Best applied to step edges. A regularized version by Catte et al- the gradient estimation for controlling the process is smoothed by a Gaussian. Proved to be mathematically well-posed. Ramp preserving complex diffusion- best for ramp-type edges. Results are smoother with almost no staircasing effects.

DES
用Matlab实现的DES算法。在Matlab窗口输入DESDECP(a,b,n),其中a,b表示16进制的明文和密钥,n为1表示加密,否则表示加密。(DES algorithm using Matlab. In Matlab window field DESDECP (a, b, n), where a, b indicates a hexadecimal plaintext and key, n is 1 shows an encryption, or that encryption.)
