A Quadrangular Sort Recognition Algorithm Based on Hough Transform
Zhi Liu · Journal of Guangxi Academy of Sciences · 2010
A quadrangular sort recognition algorithm based on the Hough Transform,according to the recognition of line and circle is proposed and proved by experimentation research testing.By means of the Hough Transform,this algorithm detects the four line segments which in the quadrangle.The abscissa's separation angles(slope) of the four line segments and the plane rectangular coordinate are worked out respectively.The four separation angles are compared after ordering them with bubble sort and the relation among the four line segments is detected.According to the parallel,vertical or intersect of line.The quadrangles are distinguished classificatorily.This kind of algorithm is proved feasible and effectual by the experimental results.
