摘　　要：针对户外禁止标识提出一种新的检测算法。首先通过路标颜色找出显著性区域,然后对满足条件的区域采用中心对称投影的方法计算其位置和尺度信息。实验证明该方法具有较高的检测率和较低的虚警率,并能满足实时应用的要求。A new detection algorithm for prohibition signs in outdoor environment is proposed.First the salient regions are found by special color of road signs and then central symmetry projection is used to find location and scale of the regions.Experiment results show that the method obtains high detection rate as well as low false alarm during real time.The algorithm meets the requirement of real-time application.
