基于小波分解重构的图像去噪程序 请多指教(Based on wavelet decomposition and reconstruction of image denoising program please enlighten)

线阵ccd信号处理，信号放大预处理，采样保持，A/D转换，分析采集的到的图像信息，确定物体位置(signal prosessing of ccd)

通过高斯、指数、瑞利、gamma、pearson、weibull模型分别对同质区域的SAR图像的强度分布进行拟合(The intensity distributions of SAR images in homogeneous regions are fitted by Gauss, exponential, Rayleigh, gamma, Pearson and Weibull models respectively.)

实现对邮票中手写字符的提取，得出灰度直方图，平滑算法，锐化算法以及输出二值化图像(Realization of the extraction of handwritten characters in stamps)

说明：  该gui函数基本上包括图像处理里面的最基本处理，相当于一个小型photoshop。比如读取文件，几何变换中的垂直镜像，平移，旋转，缩放；正交变换的DFT，FFT，DCT，DST，DHT，DWashT；灰度处理中的反色，直方图均衡，全局线性变换，分段线性变换，指数非线性变换，对数非线性变换；图像增强里面的加噪声，平滑，锐化，伪彩色增强；图像分割里面的灰度阈值法，Robert，Laplace，sobel，prewitt，canny算子边缘检测法；图像恢复里面的直接逆滤波，维纳滤波；图像编码里面的霍夫曼编码，行程编码等等(Basically, the gui functions including the most basic image processing inside the handle, which is equivalent to a small photoshop. For example, read the document, the geometric transformation of the vertical mirroring, shifting, rotating, zooming orthogonal transformation of the DFT, FFT, DCT, DST, DHT, DWashT anti-gray color processing, histogram equalization, global linear transformation , piecewise linear transformation, index of non-linear transform of the number of non-linear transformation image enhancement which increases the noise, smoothing, sharpening, pseudo-color enhancement the gray-scale image segmentation inside the threshold, Robert, Laplace, sobel, prewitt, canny edge detection operator method image restoration inside direct inverse filtering, Wiener filtering image coding inside the Huffman code, and so on Run-Length Coding)

说明：  Arnold 变换与 Gray 码变换相融合的双置乱算法程序，包括了加密和解密程序(The program of double scrambling algorithm combining Arnold transform and gray code transform, including encryption and decryption program)

说明：  BMD完整代码，包括灰度图片和彩色图片的去噪、去模糊等功能，去噪效果尤为突出。(Complete code of BMD, including de-noising and de-blurring functions of gray image and color image, especially outstanding de-noising effect.)

该Matlab程序能够去除CT扫描得到的图像的环形伪影(The Matlab program is capable of removing ring artifacts from images obtained by CT scans)

说明：  光学现象模拟，包括反射，折射，牛顿环，杨氏双缝干涉等。转自某blog(optical phenomena simulation, including reflection, refraction, Newton Central, Young's double slit interference. Transfers from a blog)

可以计算mtf，使用matlab输入图像即可实现计算(You can calculate MTF and use matlab to input images.)
