An overview of traffic sign detection methods
نویسنده
چکیده
This paper reviews the popular traffic sign detection methods prevalent in recent literature. The methods are divided into three categories: color-based, shape-based, and learningbased. Color-based detection methods from eleven different works are studied and summarized in a table for easy reference. Three shape-based detection methods are presented, and a recent method based on Hough transform is studied in detail. In the section on learning-based detection, we review the Viola Jones detector and the possibility of applying it to traffic sign detection. We conclude with two case studies which show how the presented methods are used to design complex traffic sign detection systems.

متن کاملRe-usability of traffic signs for inactive drivers with consideration of personal characteristics and sign features
There has been an increasing concern about inactive drivers who would easily lead to road accidents and fatalities once return to driving. This study investigated the re-usability of traffic signs for inactive drivers with consideration of driver factors and cognitive sign features. Fifty-seven Hong Kong Chinese, who possessed a full driving license but had not driven for an extended period, co...
