典型的角度检测算法是进行Hough变换后寻找最长直线的倾斜角度．一般情况 下，待处理图象中未必有明显的较长直线．甚至存在一些对图像进行正确检测的长直线干扰 文 章介绍了一种基于统计考虑的数据分析思路，以期在基于Hough变换的角度检测算法上取得更高 的准确性。,The perspective of a typical detection algorithm is the Hough transform to find the longest straight line after the

nonmaxsup——非最大值抑制 hysthresh——设定阈值区间，返回一个二值化图像 canny——边缘探测，图像边缘增强 adjgamma——调整图像的伽马值 findline——利用线性Hough变换和Canny边缘探测得到的线上各点的坐标 circlecoords——返回由圆的半径和圆心坐标决定的圆上各点像素的坐标 houghcircle——取一幅经过canny变换的图像，利用hough变换找到图像中的一个圆 findcircle——计算所得线上各点

This paper presents a novel approach for detecting vehicles for driver assistance. Assuming flat roads, vanishing point is first estimated using Hough transform space to reduce the computational complexity. Localization of vehicles is carried u
