计算机图形学中，用射线法和弧长法两种方法判断点是否包含在多边形内部(matlab实现) (Computer graphics, the ray method with arc-length method and two methods to determine whether the points included in the polygon internal (matlab realize))

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)

说明：  可以实现对于RGB图像进行去马赛克图像处理(demosaicing for RGB images)

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.)

matlab 极坐标图形的绘制、三维曲线、三维网格、三维阴表面明图(matlab polar graphics rendering, three-dimensional curves, three-dimensional grid, three-dimensional surface Ming Yin Figure)

说明：  c++的绘制二维等值线源码。有示例数据，可以运行。(c++ two-dimensional contour map of the source。c++ code for contour map)
