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.
MATLAB code: demo_nldif.m

Image-Compression
DCT变换1、 提取彩色图像，将图像大小限制为512*512*3；
2、 提取彩色图像三个颜色分量的矩阵，每个矩阵单独处理；
3、 将矩阵分为8*8的块，做DCT变换；
4、 提取每个块的一部分DCT系数做IDCT变换，显示基本图像；
5、 再提取每个块的一部分DCT系数做DCT反变换，得到增强层1，与前一次得到的数据叠加，得到质量更好的图像。
