一种新的水平集方法由Chunming Li教授开发的，还有配套的使用说明(A new level set method developed by Professor Chunming Li, as well as supporting the use)

利用改进的ostu即最大类间方差方法进行视频图像二值化(Ostu that the use of improved Otsu method of video image binarization)

说明：  使用halcon操作XML文件的例子，可以直接使用。仅供学习交流(Read And Write XML By Halcon)

在图像边缘点上计算边缘法向量, Compute the norm vector at the boundary(compute the norm vector at the boundary)

射线追踪算法的基础理论和学习，入门课件，适用于地震学(The basic theory and learning of ray tracing)

实现通过用户给定B样条曲线的控制顶点、设定B样条曲线的次数及类型，进而绘制出相应的B样条曲线和对应的基函数图形。并且可以通过鼠标拖拽控制顶点修改B样条曲线和对应的基函数图形。从而，对B样条曲线和基函数的性质有更深入更直观的了解，理解B样条曲线和基函数的对应关系，在以后的学习中能更好地运用B样条曲线。(The number and type of user to achieve a given control vertices B-spline curve, set the B-spline curves, and then draw the corresponding B-spline basis functions and the corresponding graphic. And can be modified by dragging the mouse to control the apex B-spline curves and the corresponding basis function graphics. Thus, the nature of the B-spline curves and basis functions have a deeper and more intuitive understanding, understanding of the correspondence between the B-spline curves and basis functions in later learning to better use of B-spline curves.)

说明：  本例程可以通过肤色进行人脸检测，同时包含一些对图像的基本处理方法，并集成了人脸识别的GUI界面。(This routine can detect face by skin color, and also includes some basic processing methods for image, and integrates GUI interface of face recognition.)

浏览图片的缩略图时，点击某张缩略图，被点击的缩略图会在当前视图放大并且全屏显示，背景用黑色透明视图遮挡。再次点击图片，将回到缩略图浏览状态(Media Focus Manager)

二维PCA-人脸识别--源程序.m个人认为比较好的,毕业设计用到啊(Two-dimensional PCA-face recognition- the source code. M personally think that a better graduation design uses ah)

matlab中值平滑处理,主要是用5点平滑和3点平滑实现(matlab median smoothing was used in 5-point smoothing and 3 points to achieve smooth)
