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.)

实现双目立体视觉中深度图的获取，程序输出结果为深度图，该方法速度比较快。(Binocular stereo vision depth map acquisition, program output as a depth map, the faster the speed of the method.)

数字图像非局部均值算法，很好的哦。我自己试过了

说明：  混合高斯背景建模，利用该方法建立动态视频中运动背景建模，得到较好效果(mixture of gaussian)

只需改变结构的内外半径即可即可求解杆状结构和管状结构的相速度和群速度的频散曲线。(Just change the structure of the inner and outer radii can be solved phase velocity dispersion curves and the group velocity of the rod-shaped structures and tubular structures.)

关系JPEG在matlab中的一些应用，给大家使用(JPEG relations in matlab some applications, to the use of U.S.)

使用3×1的结构元素，为防止越界，所以不处理最上边和最下边的两列像素(Using 3 × 1 structure elements, in order to prevent cross-border, so I do not deal with the most top and bottom of the two most pixels)

在matlab上实现用鼠标画线的功能，有利于初学matlab图像编程的人(To achieve the matlab draw lines with the mouse functions, help beginners who matlab Graphics Programming)

说明：  通过使用MATLAB语言建立三维渐开线齿轮啮合模型(use MATLAB to draw 3-D gear)
