Straight Line Segments Detection Using Nonuniformly Quantized Hough Space
Hong Liu · Journal of Chinese Computer Systems · 2008
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 computational efficiency.
