| 摘 要： | 分析图像中最近邻直线间距离和夹角的非均匀性,得到这两个参数与线段方向和长度的相关关系,并由此提出了非均匀量化Hough空间的直线检测算法NUHT (Nonuniform Hough Transform).实验结果表明,NUHT在不降低运算效率的情况下,有2倍于标准Hough变换SHT (Standard Hough Transform)的直线段检测能力,同时误报率低于SHT的1/2.

| Abstract: | Instead of quantizing Hough space uniformly as widely utilized in the SHT,Standard Hough Transform,this paper proposes a HT algorithm with nonuniform quantization of Hough space,namely NUHT,which stems from a close investigation into the angle dependency of the minimum distance and angle spacing between adjacent line segments.Experimental results show that NUHT has the capacity of detecting more than two fold straight line segments than SHT and false alarms less than 1/2 of SHT,with no decreasing in computa... |
