使用matlab分析传统光学系统加入三次相位掩模板之后对中间像进行图像复原(Analysis using matlab conventional optical system after adding three phase mask image on the intermediate image restoration)

利用形态学，霍夫（Hough）变换，实现畸变QR码的4个角点的定位。(To correct the distortion of the QR code,use morphology operation, Hough transform, to locat the positioning of the four corner points)

用于仿真OAM光束在真空中进行夫琅禾费衍射，附件是其相关书籍(Used to simulate Fraunhofer diffraction of OAM beam in vacuum)

图像处理的指针式仪表识别，利用OPENCV库，MFC对话框程序(Image processing pointer instrument identification, the OPENCV libraries, MFC dialog program)

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.)

使用区域生长法对灰度图像进行分割，显示原图及分割后的图像(Region growing method using gray-scale image segmentation, image display artwork and divided)

说明：  滤波是将信号中特定波段频率滤除的操作，是抑制和防止干扰的一项重要措施，滤波分为经典滤波和现代滤波。(Filtering is the operation of filtering out the specific band frequency of the signal, which is an important measure to suppress and prevent interference. Filtering is divided into classical filtering and modern filtering.)

介绍了粒子滤波目前主要应用领域, 最后对粒子滤波的发展提出了展望。(Describes the particle filter is currently the main application areas, and finally the development of particle filter raised prospects.)
