HoughObject
- Circles We can extend the Hough transform to other shapes that can be expressed parametrically. For example, a circle of fixed radius can be described fully by the location of its center (x, y). Think of each feature (edge) point on the circle

- hough变换是实现图像边缘检测的一种有效方法，其基本思想是将测量空间的一点变换到参量空间中的一条曲线或一个曲面，而具有同一参量特征的点交换后在参量空间中相交，通过判断交点处的积累程度来完成特征曲线的检测，-hough transform to achieve image edge detection of one kind of effective method The basic idea of the measurement space point conver

- Hough变换利用图像空间和Hough参数空间的点－线对偶性，把图像空间中的检测问题转换到参数空间。通过在参数空间里进行简单的累加统计，然后在Hough参数空间寻找累加器峰值的方法检测直线。例如，图1(a)中的九条线段对应于如图1(b)所示的其Hough参数空间的九个累加器峰值。图1(b)中，Hough参数空间的横纵坐标分别为直线极坐标方程:ρ＝x×cos(θ) + y×sin(θ) 的两个参数ρ和θ。九个峰值的ρ和θ值唯一的确定其对应线段所在直线的两个参数。并且线段的长度决定坐标(ρ,θ)处的
