- 为了提高数字图像中椭圆检测的效率和准确性,提出了一个基于最小二乘法的改进的随机椭圆检测算法. 该算法随机选取图像中的3 个边缘点,在以这3 个点为中心的窗口内,从边缘点中拟合出可能椭圆,并通过随机选 取的第4 个边缘点来确认可能椭圆. 利用直接最小二乘法椭圆拟合的特性,引入可能椭圆边缘点收集和椭圆重新 拟合的迭代过程来提取最终的椭圆参数. 通过对含有不同噪声的仿真图片和包括残缺椭圆的实际图片的实验表 明,新算法的改进是有效的. 与原算法相比,新算法降低了对参数的依赖性,提高了检测

- 基于马尔萨斯及Logistic人口模型,本文做了相应改进,根据已有数据确立了我们的人口模型。人口净增长率与人口密度比是简单常数值或者是简单的指数函数,所建立的模型来预测人口总数都是不完备的,所以我们假定人口净增长率是随总人口变化的函数,而这个函数是我们通过数据拟合可以近似得到的,由人口净增长率函数的确立,我们可以以微分方程的形式建立人口模型-Based on the Malthusian and Logistic population model, this article has done a
