The study of traffic sign detection has been of great interests and often addressed by a three-stage procedure involving detection, tracking and classification. Road safety is an issue of national concern and its impacts is on the economy, public health and the general welfare of the people. We report on-going efforts to develop an intelligent agent for detecting and tracking traffic signs for ...

This Paper presents a new hybrid technique for digit recognition applied to the speed limit sign recognition task. The complete recognition system consists in the detection and recognition of the speed signs in RGB images. A pretreatment is applied to extract the pictogram from a detected circular road sign, and then the task discussed in this work is employed to recognize digit candidates. To ...

This paper describes a method for detecting and recognizing road signs in gray-level and color images acquired by a single camera mounted on a moving vehicle. The method works in three stages. First, the search for the road sign is reduced to a suitable region of the image by using some a priori knowledge on the scene or color clues (when available). Secondly, a geometrical analysis of the edge...

The aim of this thesis project is to develop the Traffic Sign Recognition algorithm for real time. In real time environment, vehicles move at high speed on roads. For the vehicle intelligent system it becomes essential to detect, process and recognize the traffic sign which is coming in front of vehicle with high relative velocity, at the right time, so that the driver would be able to pro-act ...

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...

This paper proposes an improved color barycenter model (CBM) for road sign detection. The previous version of CBM can find out the colors of road-sign (RS), but its accuracy is not high enough for magenta and blue region segmentation. The improved CBM extends the barycenter distribution to cylinder coordinate and takes the number of colors in every point into account. Then the K-means clusterin...
