ModelingSurfwave

对于学习信号处理的同学们，需要数值分析的一些知识，如拟合、松弛迭代等等都是有用的数值分析方法(For students studying signal processing, numerical analysis requires some knowledge of relaxation that a useful method for numerical analysis)

我用C#实现的一个双边滤波器，使用unsafe代码，用指针获取像素。(I use C# to achieve a bilateral filter, use unsafe code to get pixel pointer.)

利用matlab求解超定方法，使用最小二乘法求解平面程序(Using the least squares method for solving overdetermined equations, find plane program)

霍夫曼编码n元编码，可以计算出平均码长，编码效率(Huffman coding n-ary coding, can calculate the average code length, coding efficiency)

有一学生成绩管理数据库如下表，要求建立一SAS数据集score，并输出显示 创建一个新的数据集class，新增平均成绩aver变量和等级考评grade变量，grade的值是根据aver值的大小给出A、B、C、D四个等级，并显示新数据集class(A student achievement management database as the table, called for the establishment of a SAS data set score, and output display create a new data set class, add an average score aver evaluation variables and grade level variables, grade values are based on the size of a aver value the A, B, C, D four grades, and displays the new data set of class)

background subtraction using gmm

这事我用巴特沃斯模拟的方法设计的数字低通，高通，带通滤波器，其中只有一小段(I used this method to design analog Butterworth digital low pass, high pass, band pass filter, which only a short)

这个是matlab里基于维纳滤波算法对模拟运动模糊并加入高斯噪声的图像进行复原的程序 (This is where Wiener filtering algorithm matlab simulation of motion blur and add Gaussian noise image recovery program based on conduct)

关于matkab的一点资料，是小弟精心收集的(Information on the matkab point is the collection of younger brother)

LDPC译码算法，采用LOG方法，减少计算复杂度(LDPC decoding algorithm used LOG, to reduce the computational complexity)
