用于求取三维点云数据的法向量，我的人脸建模就是用的这个，效果很好，但必须保证点云没有重叠的，否则会出现严重错误。(Strike a 3D point cloud data for normal vectors, and my face is to use this model, the effect is very good, but must ensure that there is no overlap of the point cloud, there would be a serious mistake.)

PCA IMAGE FUSION ,A GOOD MATLAB FILES

利用matlab软件仿真斜条纹和竖条纹的干涉图样(Software simulation using matlab interference pattern diagonal stripes)

说明：  Retinex算法,实现图像增强，图像质量明显提高。(Retinex Algorithm)

Nurbs曲线曲面源代码。其中包含德布尔算法计算B样条曲线，德布尔算法计算B样条曲线的导矢，B样条曲面，Nurbs曲线，Nurbs曲面。(The program code for NURBS curve and NURBS surface.)

说明：  自己编写的一个VC++程序，打开可执行程序后可以读取wave文件，此时程序将在客户区绘制波形图；之后可以计算短时能量、短时过零率和自相关函数，并且在客户区依次显示函数图像。(own VC prepared by a procedure to open executable wave after reading documents, this process will draw customers District waveform diagram; after short-term energy can be calculated, short-term rates and zero autocorrelation function, District customers in the sequence of images function.)

傅里叶轮廓变换术，通过单幅条纹图像提取相位，最后根据上述信息，模拟曲面轮廓(Contour Fourier transform technique, through single stripe image extraction phase, the last light of the above information, an analog surface profile)

用于计算在三维点云处理过程中的局部点云面积估算，精度很高。(Used to calculate the three-dimensional point cloud processing local point cloud area estimation accuracy is very high.)

【例6.4-1】本例演示：pcolor , contour, contourf的调用格式；等位线标高指令 clabel 的配合使用和区别；colorbar在用户指定位置上创建着色标尺；subplot子图位置的控制；图形窗背景底色的设置。（图6.4-1）(Example 6.4-1 This example demonstrates: pcolor, contour, contourf' s call format the bit line elevation instruction clabel of the used in conjunction with, and differences in the user-specified location colorbar create coloring ruler of the subplot subgraph location control graphics window Background background settings. (Figure 6.4-1))

An Invitation to 3d vision 一书的配套源代码，对3d视觉和3d重建感兴趣的可以看看(Source code accompany <An Invitation to 3d vision >, anyone who is interested in 3d vision and reconstruction should see this.)
