学习卡尔曼滤波器的好程序，卡尔曼滤波的程序，对于初学者而言十分经典(A good learning process Kalman filter, Kalman filtering procedure, in terms of a very classic for beginners)

数字信号处理实践方法，从一到三囊括了数字信号处理的模数变换、DFT变换、Z变换、滤波器设计等(Digital signal processing practices, from 1-3 to include digital signal processing of analog-to-digital transformation, DFT transform, Z transform, filter design, etc.)

说明：  本程序 包含两个函数 实现了 快速的沃尔什变换(This program contains two functions to achieve fast Walsh transform)

这是一个uwb用于体域网的信道仿真程序，可以进行仿真，它符合IEEE.802.15.4a，非常好！(This is a body area network for the uwb channel simulation program allows for simulation, it is consistent with IEEE.802.15.4a, very good!)

《matlab有限元分析与应用》书后源代码，在matble中运行，对于有限元的初学者很有用。("Matlab Finite Element Analysis and Application" after the source code, in matble run, FEM for beginners useful.)

The basic steps of the edge-based text extraction algorithm are given below 1. Create a Gaussian pyramid by convolving the input image with a Gaussian kernel and successively down-sample each direction by half. (Levels: 4) 2. Create directional kernels to detect edges at 0, 45, 90 and 135 orientations. 3. Convolve each image in the Gaussian pyramid with each orientation filter. 4. Combine the results of step 3 to create the Feature Map. 5. Dilate the resultant image using a sufficiently large structuring element (7x7 [1]) to cluster candidate text regions together. 6. Create final output image with text in white pixels against a plain black background.

说明：  基于MATLAB对EMD算法分解的例子，学习希尔伯特-黄变换的可以参考学习(Based on the example of EMD algorithm decomposition in MATLAB, learning Hilbert-Huang transform can be referred to.)

说明：  卡尔曼滤波，扩展卡尔曼滤波matlab工具箱。希望对大家有帮助(Kalman filtering, extended Kalman filter matlab toolbox. We hope to help)
