Abstract

To our knowledge, most machine-learning-based techniques summarize the vehicle speed, steering angle, and navigation decisions towards the raw features that extracted from the RGB images while navigating. Moreover, in recent studies, not only images were enhanced with semantic masks, but also the extracted features are enhanced with these maps, thereby providing the object’s relational feature maps based on the location of the detected objects. However, these proposed studies did not consider the saliency maps during the sign classification problems, which may provide a significant contribution to scene context understanding and complement information towards the vehicle’s navigation decisions. Moreover, it would be interesting to investigate how to aggregate saliency information and navigation, while respecting traditional sign classification and detection. Sign-level state information includes not only the traffic signs but also their distances and locations. Therefore, integrating not only the fused feature maps, but also the distance information, which is an essential information about the closeness of the signs to our vehicle, is an important point in recognizing the traffic signs.
