摘要
将Steger曲线结构检测器与过零点检测相结合,提出一种新的亚像素提取算法,并通过实验验证了此方法的有效性。
In this paper, a method for detecting sub-pixel points based on zero-crossing detection combined with Steger＇s curvilinear detector has been presented. Finally, the feasibility and validity of this method has been confirmed by the experiment.
