利用harris算法进行角点检测，然后利用鼠标将角点的坐标读取出来，存到数组当中(harris corner detection)

何凯明的《Single Image Haze Removal Using Dark Channel Prior》论文中的代码，基于暗原色先验的图像去雾算法，对户外图像去雾有很好的效果(this code is of the paper"Single Image Haze Removal Using Dark Channel Prior",the function is removing haze based on Dark Channel Prior algorithm , having a good effect on outdoor images.)

参考Matlab提供的模块建立简化的三相锁相环的仿真模型，只保留必要的步骤，如abc-dqz只计算Vq，去除频率反馈模块和自动参数调整模块等。 建立单相锁相环的计算模型  简化单相锁相环的系统结构，保留必要的PI控制器等模块  验证并讨论输入信号频率在45-65Hz变化时设计的锁相环的动静态性能  仿真并分析三相输入信号包含谐波、不平衡和直流偏移时锁相环的锁相结果(Reference Matlab provides three-phase PLL module to establish a simplified simulation model, retaining only the necessary steps, such as abc-dqz counting only Vq, remove frequency feedback module and automatic parameter adjustment module.  simulation and analysis of the three-phase input signal contains harmonics, unbalance and DC offset PLL phase-locked Results)

在建模中方程求根时用到的matlab程序，可以更加迅速(Roots of equations in modeling when used matlab procedures can be more quickly)

在土工三轴试验中应用该方法使得试样的变形测量更加简便。通过使用高精度标定板，对该数字图像测量方 法进行了精度分析，结果表明亚像素角点检测方法的轴向和径向测量的标准差都达到了0．02个像素，相对测量精度达到10‘4 数量级。(Triaxial tests in application of this method makes it easier specimen deformation measurements. By using high-precision calibration board, the digital image analysis to measure the accuracy of the method, the results of the standard deviation to measure the axial and radial table Minya pixel corner detection methods have reached 0.02 pixels, relative measurement accuracy of 10 ' 4 magnitude.)

说明：  确定虚警概率，进行2000次蒙特卡罗实验，将检测成功的概率绘成ROC曲线(Determine the probability of false alarm, conduct 2000 Monte Carlo experiments, and draw the probability of detection success into ROC curve)
