OBJ文件读取程序：可以读取ASCII格式OBJ后缀的3D图形文件中的数据信息，并显示在屏幕上(a MATLAB program which gets the name of an ASCII OBJ file from the user, reads the 3D graphics information stored in the file, and displays the structure on the screen)

著名的FastICA 算法,最新版本,修改了以前的Bug,(The famous FastICA algorithm, the latest version, modify the Bug before,)

这是一篇关于超声相控阵二维面阵实现三维成像的文章，很不错。(This is an article on ultrasonic phased array two-dimensional array of three- dimensional imaging article, great.)

说明：  三维重建是指对三维物体建立适合计算机表示和处理的数学模型,是在计算机环境下对其进行处理、操作和分析其性质的基础,也是在计算机中建立表达客观世界的虚拟现实的关键技术。(Three-dimensional reconstruction refers to the establishment of a mathematical model suitable for computer representation and processing of three-dimensional objects. It is the basis for processing, manipulating and analyzing their properties in the computer environment. It is also the key technology for establishing a virtual reality to express the objective world in the computer.)

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.)

说明：  根据离散数据点拟合圆，得到圆心坐标和拟合半径(Fitting the circle according to the discrete data points, the coordinates of the center of the circle and the fitting radius are obtained.)

Voronoi图是以两点间线段的长度作为距离 ,对平面的一种分割。然而 ,在地理环境中 ,存在着许多自然的或人为的障碍 ,使得从一点到另一点不能直线到达。为了扩大Voronoi图的应用领域 ,本文对传统的Voronoi图进行扩充 ,给出了障碍Voronoi图的定义、性质 ,以及离散生成线段障碍Voronoi图的方法(Voronoi diagram based on the length of line between two points as the distance from a partition of the plane. However, in the geographical environment, there are many natural or man-made obstacles, making from one point to another point of arrival can not be a straight line. In order to expand the area of Voronoi diagram, Voronoi In this paper, the traditional expansion plans, given the obstacles to the definition of Voronoi diagram, the nature of the discrete Voronoi diagram generation segment of the barrier method)

制作二维地形,并且可以对其添加线表示，还可以做分层设色二维地形图图(Dimensional terrain)

Laplasian图像边缘提取，亲测有效，欢迎下载使用。(Edge extraction of Laplasian image)

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)
