双曲线回归方程 HyperbolaRegress.cs
注意!该模型要求a与b的值要大于0!使用该模型时应注意验证这个限制条件。我在实现模型时未加入任何出错流程控制。X不能为0。
方程模型为
public override double[] buildFormula()
得到系数数组,存放顺序与模型系数相反,即该数组中系数的值依次是b,a。
public override double forecast(double x)
预测函数,根据模型得到预测结果。
public override double computeR2()
-Hyperbola regression equation HyperbolaRegress.cs attention! The model demands a and b value is greater than 0! Caution should be taken when using the model verify the conditions of this restriction. I realize the model error is not to join any flow control. X should not to 0. Equation model for public override double [] buildFormula () get coefficient array, the storage order and model coefficients contrary, that is, the array is followed by the value of coefficient b, a. public override double forecast (double x) prediction function, according to the results of model prediction. public override double computeR2 ()

基于蚁群优化的图像边界检测
应用背景图像边缘是很重要的视觉信息,边缘检测在图像处理和机器视觉中占据着重要位置。通过边缘检测勾画出目标物体的轮廓,达到目标识别的目的。传统的边缘检测方法是基于空间运算的,借助空域微分算子利用卷积来实现,主要起到高通滤波的作用,如Sobel边缘算子、Roberts边缘算子、Krisch边缘算子、高斯2拉普拉斯边缘算子等关键技术
信息激素(Pheromone)作为蚂蚁选择后续行为的依据,并通过蚂蚁间的协同与交互来完成全局寻优搜索过程。该算法具有强鲁棒性、正反馈性和分布式处理等特点,已被成功用于解决许多诸如TSP问题、图着色问题等复杂问题。但用于图像处理领域,国内外的研究还比较少,韩彦芳等人利用蚁群算法提出了基于模糊聚类的图像分割方法,本文则利用蚁群算法提出了一种新的图像边缘检测方法。将一群蚂蚁随机放置到图像中,根据蚁群算法的路径选择机制,使蚂蚁以较大的概率选择图像边缘点作为下一步移动目标位置,经过多次循环迭代最终使大多数蚂蚁聚集到图像边缘上,从而提取出图像的边缘。

蒙特卡罗方法又称随机抽样技巧或统计试验方法。半个多世纪以来,由于科学技术的发展和电子计算机的发明 ,这种方法作为一种独立的方法被提出来,并首先在核武器的试验与研制中得到了应用。蒙特卡罗方法是一种计算方法,但与一般数值计算方法有很大区别。它是以概率统计理论为基础的一种方法。由于蒙特卡罗方法能够比较逼真地描述事物的特点及物理实验过程,解决一些数值方法难以解决的问题,因而该方法的应用领域日趋广泛。
-Monte Carlo method known as random or statistical skills test method. More than half a century, the development of science and technology and the invention of the electronic computer, this method as an independent method was raised and the first nuclear test and research has been applied. The Monte Carlo method is a calculated, but with the general numerical method a great difference. It was based on the theory of probability and statistics-based approach. As the Monte Carlo method can vividly describe things and the physical characteristics of the experimental process, numerical methods to solve some difficult problems, the result of the increasingly extensive application areas.
