kalman滤波的经典例程，对于学习和指导使用kalman滤波非常有帮助，还附有Kalman最经典的论文A New approach to Linear filtering and prediction problems以及非线性系统确定采样型滤波算法综述2012控制与决策(kalman filtering classic routines, learning and guidance for using kalman filter is very helpful, but also with Kalman most classic treatise A New approach to Linear filtering and prediction problems and nonlinear systems reviewed to determine the sample type filter algorithm 2012 Control and Decision)

The guided filter can be used as an edge-preserving smoothing operator like the popular bilateral filter, but has better behaviors near edges. The guided filter is also a more generic concept beyond smoothing: it can transfer the structures of the guidance image to the filtering output, enabling new filtering applications like dehazing and guided feathering. Moreover, the guided filter naturally has a fast and non-approximate linear time algorithm, regardless of the kernel size and the intensity range. Currently it is one of the fastest edge-preserving filters.

这三个小程序都是matlab的.m文件，分别实现用灰度变换的方法增强图像的对比度和直方图均匀化，模拟图像受高斯白噪声和椒盐噪声的影响。(The three procedures are Matlab. M documents, were used to achieve gray transform method to enhance the contrast of the image and histogram equalization. Simulation images by white Gaussian noise and the noise of Salt and Pepper.)

matlab仿真匹配滤波器程序，很不错的(Matlab simulation matched filter procedures, very good)

做了詞法分析器，不知道怎樣，希望有人給我提提意見(Done a lexical analyzer, I do not know how, I hope someone is going to give me make a suggestion)
