摘要
在图像处理和计算机视觉中,Hough变换(HT)是一种应用非常广泛的图像边缘检测技术,但HT还存在许多问题,例如,存储空间需求太多,计算量太大,可能产生冗余点和虚交点.存在重复线段,阈值选择困难等.本文提出了一种快速Hough变换(FHT)的改进算法,可以有效解决上述问题,同时提高计算速度方面有非常明显的优势.
This paper presents a new algorithm for th fast Hough transform(FHT). Compared with others this algorithm not only bas a faster speed but also has advantage such as avoiding erroneous sloutions,liminating re- dundant points deeteccting straight lines of different sizes and selecting threshold autmatically etc. We also discuss the prformance of this algorithm and show its effcincy with exampls in this paper.
