New line detection method by edge division based on Hough transform
Жипенг Ли · Journal of Computer Applications · 2010
Hough transforms is a well known technique for line detection.However,it is difficult for most existing methods to extract line segments from noisy images,mainly because some objects have non-line edges,or some objects have close line edges.To solve the problem,this paper proposed a novel method that partitions the upper edge and the lower edge of the image in image space and then dynamically get the peaks in accumulator space in a novel peak detection method.In the experiments,three algorithms were tested on three different images.The results show that the proposed method is superior to existing methods in terms of accuracy and robustness.
