频域滤波器

压缩包里面为2个程序，一个是悬链线模拟索的程序，一个是抛物线法模拟的索的程序(Compressed inside of two programs, one cable catenary simulation program, a parabolic law analog cable programs)

线性反投影算法（Linear Back Projection，简称 LBP）又称累加法，是最早使用的一种简单（ECT图像重建）成像算法。它将通过某点的所有投影射线进行累加，再反向估算出该点的密度值。从成像观点分析，它是不完全的雷登逆变换（完整的雷登逆变换包括微分、希尔伯特变换、反投影和归一化等步骤）。(Linear back projection algorithm (Linear Back Projection, referred LBP), also known as cumulative method, is the first to use a simple (ECT image reconstruction) imaging algorithms. It accumulates all projection rays through a point, then reverse the estimated density value of the point. From the image point of view analysis, it is not exactly the inverse transform Leiden (Leyden complete inverse transformation involving differential Hilbert transform backprojection and normalization steps, etc.).)

序列匹配c++实现，可以帮助理解序列匹配算法(Sequence matching c++ implementation can help to understand the sequence matching algorithm)

运用计算机图形学的知识，采用4阶B样条基函数，节点向量取为[0,0,0,0,1/4,2/4,3/4,1,1,1,1] 先绘制控制多边形，再用分段直线段绘制B样条曲线(Using the knowledge of computer graphics, the 4 order B spline basis function is used, and the node vector is taken as [0,0,0,0,1/4,2/4,3/4,1,1,1,1]. First, draw the control polygon and draw the B spline curve by piecewise straight line segments.)

08年新的Delaunay程序，很不错的！(Delaunay new 2008 program, it is good!)

SARBM3D matlab code for image preocessing

新兴起的一种分解方法，比小波分解更精确。 在纹理回复时候应用(The emergence of a new decomposition method, more accurate than the wavelet decomposition. Back in time for the application of texture)

gabor小波变化的实现，用于数字图像处理中Gabor特征的完全提取。自己项目中已经用到了。(Achieve gabor wavelet transform for digital image processing totally Gabor feature extraction. Himself has used the project.)

说明：  外国人写的CANNY边界检测算法，代码质量很高，对初学编程很有帮助。(Foreigners write CANNY edge detection algorithm, code quality is high, very helpful for beginners programming.)

运用微粒群算法求解改进的二维熵最大值算法，对于医学图像分割非常有用(Using the PSO algorithm to calculate the maximum of the improve 2D entropy value)
