摘要：Hough变换可以使边界检测达到亚像素级别，但需要花费很多时间。本文提出一种具有指定精度且可变步长的迭代算法，在钢板影像识别检测中进行试验，结果表明：改变步长的亚像素探寻时间效率比整个行程内进行遍寻的亚像素探寻更高。

Application of Subpixel Hough Transform Based on Variable Step Size
in Plate Image Recognition and Detection

Abstract:Although Hough transform can make boundary detection to reach subpixel level，which takes a lot of time.An iteration algorithm with specified precision and variable step size is proposed.Experiments are carried out in steel plate image recognition and detection.The results show that the time efficiency of subpixel searching with changing step size is much higher than that of subpixel searching with traversal in the whole journey.
