A study on image features for visibility estimation of traffic signs using in-vehicle camera

This paper reports a study on image features for visibility estimation of traffic signs using in-vehicle camera. Recently, the kinds of driving support systems in a car is increasing. As a result, it is becoming more important to select appropriate information from them for safe and comfortable drive because too much information may cause driver distraction and may increase the risk of a traffic accident. One of the approaches to avoid such a problem is to alert the driver only information which is easy to miss. Therefore, to realize such a system, we focus on estimating the visibility of traffic signs which show a driver important traffic information. In this paper, we pick several features and show the experimental results on their effectiveness.
