用对偶分裂算法处理乘性噪声如盐椒噪声（L1+TV），参数由电脑自动选取，matlab程序(A Duality-Based Splitting Method for L1-TV Image Restoration with Automatic Regularization Parameter Choice)

chan-vese几何活动轮廓提取 讲物体的裂痕非常精准的提取出来 非常经典的并且最新的代码 可供参考 (chan-vese geometric active contour extraction rift speak very precise object extracted from a very classic and the latest code for reference)

说明：  slic超像素分割，可以实现图像的超像素分割(SLIC super pixel segmentation)

光流法、帧间差分法、高斯背景模型差分法，在opencv环境下实现运动目标检测(moving objective detection matlab)

说明：  基于MATLAB语言，计算两幅图像峰值信噪比和均方差。(Computing Peak Signal-to-Noise Ratio and Mean Variance of Image)

说明：  matlab水果识别器，形态学，识别五种水果，要求背景较简单边缘明析(matlab fruit recognizer, morphology, recognition of five kinds of fruits, requiring simple background and edge)

说明：  matlab输入CAD图像文件，matlab中图形导入CAD，matlab与CAD互转(Matlab Input CAD Image File or graphics Import into CAD in matlab or matlab and CAD Interchange)

利用低通滤波器对图像进行插值放大：按放大的倍数对原图像进行插零，插零后的图片与低通滤波函数进行卷积，原先插入的零的位置自动替换为适当的插值，如此图像就已经插值放大了，图像质量还不错。(Double the number of pixels of each row and column by adding a zero value pixel between each pixel of the image.Then operate with two kinds of low-pass filters to get the enlarged image.)

该m文件是用来仿真合成孔径雷达SAR的斑马图，即菱形图的，是本人自己设计的，可用。(M file is used to simulate the synthetic aperture radar SAR zebra figure, namely diamond chart, is my own design, is available.)

数学地角度来看，信号与图像处理可以统一看作是信号处理（图像可以看作是二维信号），在小波分析地许多分析的许多应用中，都可以归结为信号处理问题。对于其性质随时间是稳定不变的信号，处理的理想工具仍然是傅立叶分析。但是在实际应用中的绝大多数信号是非稳定的，而特别适用于非稳定信号的工具就是小波分析。(Mathematically, signal and image processing can be regarded as signal processing (image can be regarded as two-dimensional signal). In many applications of wavelet analysis, they can be reduced to signal processing. For signals whose properties are stable over time, the ideal tool for processing is still Fourier analysis. However, most of the signals in practical applications are unstable, and the tool especially suitable for unstable signals is wavelet analysis.)
