三维三自由度机器人仿真程序，可以离线编程(3D three-robot simulation program can OLP)

3D图形编程，让你形象的看到一座山峰，同时也能举一反三运用到其他画图的方面。(3D graphics programming, so you see the image of a mountain, but also can be applied to other aspects of replicability drawing.)

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,)

说明：  给定一个图像，其中包含足够的信息来计算地平面消失线和垂直消失点，以及一个已知高度的物体。然后，只要他们的头部和脚都可见，就可以在场景中的任何地方测量站在地平面上的人的高度。(Given an image which contains sufficient information to compute the ground plane vanishing line and the vertical vanishing point, and also one object of known height for which the top and base are imaged. Then the height of a person standing on the ground plane can be measured anywhere in the scene provided that their head and feet are both visible.)

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)

说明：  基于图像序列的单目三维重建，运用运动恢复结构，SIFT算法等(Monocular 3D reconstruction based on image sequence, using motion recovery structure, SIFT algorithm, etc.)

实现三维对象的平移,旋转变换,以及投影变换,不错的(Realize 3 d object of translation, rotation transformation and projection transformation, good)

computer graphics 2d programs

是一篇国外的图形文章代码，将输入图像的2D轨迹转化为3D图形(Is a foreign article graphics code will be entered into 2D images into 3D graphics trajectory)

最大类间方差法是由日本学者大津(Nobuyuki Otsu)于1979年提出的,是一种自适应的阈值确定的方法,又叫大津法,简称OTSU。它是按图像的灰度特性,将图像分成背景和目标2部分。背景和目标之间的类间方差越大,说明构成图像的2部分的差别越大,当部分目标错分为背景或部分背景错分为目标都会导致2部分差别变小。(The largest between-class variance method was proposed by the Japanese scholar Nobuyuki Otsu in 1979. It is an adaptive threshold determination method, also known as the Otsu method, or OTSU for short. It is based on the grayscale characteristics of the image and divides the image into two parts: the background and the target. The larger the variance between the background and the target, the greater the difference between the two parts that make up the image. When the part of the target is wrongly divided into backgrounds or part of the background is mis-divided into goals, the difference between the two parts will be smaller.)
