matlab灰度图像的边缘提取：直方图均衡化，canny算子实现一阶偏微分，计算梯度幅值和方向(matlab Gray Image Edge Extraction: histogram equalization, canny realization of first-order partial differential operator, calculate the gradient magnitude and direction)

这个是霍夫曼编码的问题，要求输入只含有ABCD的四句话，且每句8个字符的长度，然后求出四个字符每个的概率，然后当成权值计算霍夫曼编码，我的这个程序已经实现了输入、概率统计、计算出霍夫曼编码存在了bian[]这个数组中(hoffuman decoding)

利用GNSS 进行高精度导航定位的前提是正确固定载波相位观测值的整周模糊度。由Galileo 系统的4 个载波观测值可以 形成诸多有良好特性的组合观测值,利用这些组合观测值,结合MCAR 方法,可以有效地确定整周模糊度。(The use of high-precision GNSS navigation and positioning the premise is correct carrier phase observations fixed integer ambiguity. May consist of four carriers observations Galileo system There are many good characteristics to form a combination of observations using a combination of these observations, combined with MCAR method can effectively determine the integer ambiguity.)

WINDOWS下可可播放多媒体文件和其它 (Under WINDOWS cocoa to play multimedia files and other)

说明：  MFC实现页面置换，可视化！ 先入先出法（FIFO） 最优置换算法（OPT） 最久未使用算法（LRU） (AppWizard has created this group_20 application for you. This application not only demonstrates the basics of using the Microsoft Foundation classes but is also a starting point for writing your application.)

Visual C虚拟示波器源码可以通过此源代码学学习相关频谱显示功能 ， (Visual C virtual oscilloscope source can learn through this source code to learn the relevant spectrum display)

C语言实现数字信号处理信号过系统（FIR、IIR型滤波器，含画图子函数。） 需：include"graphcis"(C-signals over the digital signal processing systems (FIR, IIR filters, including drawing subroutine.) Must: include " graphcis" )

剪贴板通信--虽然程序很简单，但是很好地解析了进程和线程的原理，是运用进程和线程的小例子(Clipboard communication- although a simple process, but the good analysis of the principles of process and thread, is to use a small example of the process and thread)
