说明：  对于给定的滤波器参数，利用脉冲响应不变性法设计数字低通滤波器，并绘出了设计后的数字滤波器的特性曲线。(This code uses impulse invariant method to design a digital low-pass filter under given filter parameters,then it plots the designed filter s characteristic curve.)

compressive sensing theory

这是背包问题的程序，用matlab实现，背包问题是NP完全问题(This is the knapsack problem program, using matlab , knapsack problem is a a NP-complete problem)

1.实验目的：绘制分形图案并分析其特点。  2.实验内容：绘制Koch曲线、Sierpinski三角形和树木花草图形，观察这些图形的局部和原来分形图形的关系。  3.实验思路：利用函数反复调用自己来模拟分形构造时的迭代过程，当迭代指标n为0时运行作图操作，否则继续迭代(1. Purpose: Draw fractal patterns and analyze their characteristics. 2. Experiment: Draw Koch curve, Sierpinski triangle graphic flowers and trees, observe the relationship between the local and original graphics fractal graphics. 3. Experiment idea: using the function calls itself repeatedly to simulate the iterative process when the fractal structure, when the iteration index n is plotted 0:00 run, otherwise continue iterating)

基于matlab将商标与文字分割，选定阀值，先进行次分割，在进一步优化(Matlab-based trademarks and text segmentation, the selected threshold, the first for sub-division, in further optimization)

new sharpening concept

特征提取算法 一篇经典的英文文献 介绍了一种新的算法 模式识别(Feature extraction algorithm，a classic English literature describes a new algorithm for pattern recognition)

说明：  低密度奇偶校验码（LDPC）的matlab仿真(Low Density Parity Check (LDPC) of matlab simulation)

初学matlab的教程，比较全面，比较实用，此部分为第二部分。(Matlab beginner tutorial, more comprehensive, more practical, this part of the second part.)

利用k-means的算法实现图像区域分割，主程序只能运行灰度图像，彩色图像需另写调用程序(Using the k-means algorithm for image segmentation, the main program will only run grayscale image, color image subject to write the calling program)
