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.)

说明：  求解在一个三角形上的任何一点，到另外一点的距离最小的一个点。(solution in a triangle on any point to another point of the smallest distance between a point.)

自己编写的C++小程序，十字算法，用到KD树，能够有效进行点云去噪，压缩数据(I have written a small program C++, cross algorithm used in KD tree, the point cloud can be effectively de-noising, compression of data)

图像读入读出系统(image reading system to read)

各种矩阵算法库,支持UpperTriangularMatrix,LowerTriangularMatrix, Diagon()

用于各种特征提取主成分分析法，如表情提取，人脸提取，识别分类等(For a variety of features to extract the principal component analysis (pca)，Such as expression extraction, face extraction, identification classification, etc)

说明：  用于rtd2660方案OSD内字体生成，可以做开机LOGO，无信号界面等(It is used for font generation in OSD of rtd2660 scheme, and can be used for power on logo, signal free interface, etc)

心电信号去噪，主要针对的是基线漂移噪声,肌电噪声和工频干扰 (Is mainly targeted at the baseline wander and power line interference, noise)
