用背景建模和前景分割的方式把运动车辆提取出来
该程序混合高斯模型使用K(基本为3到5个) 个高斯模型来表征图像中各个像素点的特征,在新一帧图像获得后更新混合高斯模型,用当前图像中的每个像素点与混合高斯模型匹配,如果成功则判定该点为背景点, 否则为前景点。通观整个高斯模型,他主要是有方差和均值两个参数决定,,对均值和方差的学习,采取不同的学习机制,将直接影响到模型的稳定性、精确性和收敛性。由于我们是对运动目标的背景提取建模,因此需要对高斯模型中方差和均值两个参数实时更新。

这是一个简单的演示如何评价文本的数学表达式
This a simple demo of how to evaluate mathematical expressions in text
format, including provision for variables and functions. The code consists of
three simple classes: 1) Calc - which does the main calculations, 2) Stack -
which is used to push and pop intermediate operators and numbers and 3)
Symbol Table. The symbol table is a collection of calc symbols, a type structure
consisting of various elements, including the expression name, function name,
and the final value of the expression The evaluation procedure is done in three
steps: 1) simplify the expression by removing all the elements within () and
storing them in subexpressions within the symbol table. 2) Each of these sub
expressions are then converted to RPN format (Reverse polar notation) and
evaluated 3) Finally, the main expression is converted to RPN and evaluated-This is a simple demo of how to evaluate mathematical expressions in text
format, including provision for variables and functi

线性方程组的求解
1.通过这次实验,我掌握了使用Gauss消去法解线性方程组的方法,加深了我对Gauss消元法的理解。2.Gauss消元法还可以改进,可衍生出列主元消去法和平方根法等,达到减少计算量和减小误差的作用使结果更加准确。3.迭代过程中要求主对角线元素不为零,这在一定程度上限制了可解的线性方程组。
