A New Approach to Traffic Sign Recognition
نویسندگان
چکیده
A new approach has been developed for accurate and fast recognition of traffic signs based on human vision models. It applies colour appearance model CIECAM97 to segment traffic signs from the rest of scenes. This model takes viewing conditions into account and can recognise colours as accurate as an average observer invariant of lighting sources, background, and surrounding colours. A Behavioural Model of Vision (BMV) is then used to identify the signs after segmented images are converted into gray-level representation. The BMV is transform invariant and can recognise most signs with distorted shapes. Two standard traffic sign databases are established. One is British traffic signs and the other is Russian traffic signs. Preliminary results show that around 90% signs taken from the British road with various viewing conditions have been correctly identified.

متن کاملA New Approach for Circular Traffic Sign Tracking from Image Sequences
This paper describes a new approach for tracking circular traffic signs from image sequences. As a part of traffic sign recognition system, the traffic sign tracking will improve the performance of the recognition. By tracking the signs, search space is reduced and misdetection caused by temporal occlusion could be avoided. We propose a new blob tracking called two-layer blob tracking to track ...
