Description

The ability of line extraction from a image by the Hough Transform is strongly affected by the quantization error of the image and the Hough space.We have proposed a new method ″Vaxiable Hough Transform(VHT)″ to improve the extraction ability.In VHT,2D- distributed voting is performed by using a Variable Filter.This paper proposes a Laplacian-of-Gaussian filter as the optimum Variable Filter.This filter is constructed from the frequency analysis of the Hough space by Radon Transform and Fourier Transform.The lower bound and the optimum filter size is calculated from the analysis and the mathmatical analysis. Experiments show that the filter can improve the ability and the accuracy better than usual Hough Transform and previous VHTs.
