说明：  对二维数据进行变分模态分解，可用于地震数据去噪等(Variational mode decomposition of two-dimensional data can be used for seismic data denoising, etc.)

说明：  主动光学三维传感技术中的相位展开算法——二维菱形算法(Active optical sensing technology in three-dimensional phase unwrapping algorithm- Algorithm for two-dimensional diamond)

这是单幅图片中的椭圆目标与方向位置检测matlab 程序(ellipse detection and position detection)

3d 图形变换相关的代码,借助现有的一些几何库，实现了如三角网格化简 参数化等的内容(3D model tranform code)

说明：  访问最底层LOD模型路径，打开后获取顶点数据和PirmitiveSet，重绘模型的三角面片(Visit the bottom LOD model path, open it, get vertex Array and PirmitiveSet, and redraw the triangle of the model.)

说明：  三维均匀介质的高阶交错网格弹性波方程数值模拟（未加PML吸收边界条件），模拟结果以切边形式显示(Numerical simulation of three-dimensional homogeneous medium of high-order staggered elastic wave equation (not PML absorbing boundary conditions), the simulation results are displayed in the form of trimming)

对输入的图象用Kirsch算子进行边缘检测,参数K用来调整边缘的多少(The input image by Kirsch edge detection operator, parameter K used to adjust the edge of the number of)

包含拉东正向变换和反拉东变换及使用双曲拉东变换去除多次波(Radon contains forward transform and inverse Radon transform and the use of hyperbolic Radon transform to remove multiple wave)

说明：  在matlab中读取stl切片文件，形成点云数据(Read STL slice file in MATLAB to form point cloud data)

说明：  通过设置5个不同的时域窗尺度和8个方向（theta），得到40个Gabor滤波器。但在滤波器显示的时候出现了问题。以下分别把程序的源代码、调用代码(Forty Gabor filters are obtained by setting 5 different time window scales and 8 directions (theta). But there was a problem when the filter was displayed. The following procedures are the source code, call code)
