A Real World Detection System - Combining Color, Shape and Appearance to Enable Real-time Road Sign Detection
نویسندگان
چکیده
Although specific object detection has undergone great advances in recent years, its application to critical real-time circumstances like those in automated vehicle controlling is still limited, especially when facing strict speed and precision requirements. This paper uses a hybrid of various computer vision techniques including color space analysis, Haar-wavelet cascade detector, contour analysis and RANSAC shape-fitting, to achieve a real-time detection speed while maintain a reasonable precision and false-alarm level. The result is a practical system that out-performed most rivals in an automated vehicle contest and an indication of feasible CV application to speed critical areas.

An Automatic Road Sign Recognition System {A(RS)2} is aimed at detection and recognition of one or more road signs from real-world color images. The authors have already proposed an A(RS)2 able to detect and extract sign regions from real world scenes on the basis of their color and shape features. Classification is then performed on extracted candidate regions using Multi-Layer Perceptron neur...

Abstract: A system for real-time traffic sign detection is described in this paper. The vision-based traffic sign detection module developed in this work is intended for assisted driving of road vehicles by handling color images in RGB (Red, Green and Blue) format. In a first step a preattentive area of interest is determined based on the vertical projection of edge pixels. In a second step, a ...
