石墨烯的结构编程图,这是费了工作人员很长时间才完成的。(The figures of graphene)

光斑的中心提取：重心法和圆拟合。先用多次迭代求阈值并且对图像二值化，再用重心法和圆拟合提取光斑中心。(light spot method：median point ，circle fitting)

说明：  几何变换，能实现二维图像的平移，旋转和放缩功能。(geometric transformation, 2D images to achieve the translation, rotation and scaling functions.)

说明：  通过设置5个不同的时域窗尺度和8个方向（theta），得到40个Gabor滤波器。但在滤波器显示的时候出现了问题。以下分别把程序的源代码、调用代码(Forty Gabor filters are obtained by setting 5 different time window scales and 8 directions (theta). But there was a problem when the filter was displayed. The following procedures are the source code, call code)

用python实现简易计算器，包括+，-，*，/及一些扩展运算，是联系python的GUI编程的很好的练手题目。(simple calculator write by Python.)

仿射变换,2D图形编程,图形图象,有matlab操作界面，可实现任意二维变换(Affine transformation, 2D graphics programming, graphics, images, has matlab interface can realize any two-dimensional transform)

说明：  电磁波在均匀等离子体中的传输，等离子体密度适中(microwave propagation in uniform plasma)

根据教程自己写的对单目相机的标定，以及对一张镜像畸变图像的矫正，最后进行二维测距，根据像素值测得一条平面曲线的真实长度(According tutorials to write their own right monocular camera calibration, as well as a mirror image distortion correction, the final two-dimensional distance, measured according to the pixel values ​ ​ of the true length of a plane curve)

在有障碍的环境中，有效避障搜索，到达目标点。(In an obstacle environment, effective obstacle avoidance search can reach the target point.)

通过图像模板匹配，完成数字图像的平面应力与应变分析(Complete plane stress and strain analysis of digital image)
