Investigation on Preprocessing of Line Extraction
摘要
Abstract
Although traditional line extraction algorithms are effective for standard lines,they are not applicable to atypical lines. The lines in image are blurry since there is noise in many applications,and sufficient information cannot be acquired with the general method of line extraction. To extract sufficient line information in noised image accurately,a method for extracting atypical lines by combining fractal ge-ometry and Hough transform has been proposed,with car plate and Oracle character shape as the examples. It adopts the approach based on fractal geometry to realize computer-assisted restoration for atypical lines. After computation of fractal dimensions of atypical lines ed-ges,compressing and transforming of their edges,the shape of concaves or convexes for atypical lines since noise is smoothed and their o-riginal shape are restored,extraction of straight lines by Hough transform. The experimental results show that more information has been extracted from the smoothed atypical lines and that the method of fractal geometry with Hough transform is effective.关键词
