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

首先检测图像中相邻的像素点并进行聚类, 形成一些相连的像素点的集合, 然后将聚类
后的像素点进行感知编组, 细分成比原聚类线段更接近直线的线段, 最后对每段近似直线用随机 Hough变换进行检测-First detection in adjacent pixels of the image and clustering, form some connected set of pixels, then clustering
Pixels after perception marshalli

The Hough transform is a well-established scheme for detecting digital line components
in a binary edge image. A key to its success in practice is the notion of voting on an
accumulator array in the parameter plane. This paper discusses computati
