光线跟踪算法，能显示基本图形（球形，立方体，墙面），实现阴影，高光，反射，折射等效果(Ray tracing algorithm, can display basic graphics (sphere, cube, wall), to achieve shadows, light, reflection, refraction and other effects)

图像质量评价中全参考方法IWSSIM的代码，是经典方法SSIM的升级(The code of IWSSIM, a full reference method in image quality evaluation, is an upgrade of SSIM, a classical method)

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.)

自己开发的一种点云降噪方法，可以去除物体主体之外的部分的点云数据（物体点云数据为三维扫描仪获得）(A point cloud noise reduction method developed by ourselves can remove part of the cloud data outside the main body of the object (object cloud data is obtained for a three-dimensional scanner))

连续小波变换寻找脊线，用在信号处理、图像处理等方面（MATLAB）(Continuous wavelet transform for ridge line（MATLAB）)

说明：  二维原始Otsu算法的MATLAB实现和其对应的文献。实现效果很好。(MATLAB realization of two-dimensional original Otsu algorithm and its corresponding literature. To achieve good results.)

说明：  本人依据一篇文献介绍的方法编的彩色图像边缘检测程序，其效果要由于一般的方法。(literature on the basis of a methodology for the Color Edge Detection procedures, the effect due to the general approach.)

说明：  利用meanshift算法对图像进行滤波。meanshift可用于滤波、追踪、聚类、分割等(The image is filtered by means of shift algorithm. Meannshit can be used for filtering, tracking, clustering, segmentation, etc.)

说明：  图像自适应阈值分割，基于直方图的图像阈值分割(Image adaptive threshold segmentation)

运用本征模式匹配理论研究了声子晶体实际的声学速度沿两个高度对称的方向上的第一布里渊区里的特性。(The effective acoustic velocity along two highly symmetric directions of the first Brillouin zone is studied in a two-dimensional squarely arranged solid-solid phononic crystal.)
