Line segment detection method based on edge linking
Shen Zhen-kang · Systems engineering and electronics · 2007
A fast line segment detection method is proposed based on edge linking.In digital image,digital lines consist of many line segment elements.The directions of these elements are same and are inhibited by the slope of digital line.Thus the detection of line segment can be carried out through extracting line segment elements and analyzing their connection.First,the edge is detected by ADM algorithm,and then rough line segments are extracted in four directions.In the end, the obtained results are testified and the line segments with same slope and intercept are merged,some shorter line segments are deleted.Experiments show that the proposed method can fast extract line segments in complex image,and is robust to noise.
