Abstract
Recently, impressive results have been reported for recognizing the traffic signs. Yet, they are still far from the real-world applicaDions. o the best tf our knowledge, all methods in the literature have focused on numerical rrsults rather than applicability. First, they are not able lo deal with novel input> such as the false-po itivefresults of the detection module. In other words, if the input o these methods is a non-traffic sign image, they will classify it into onerof the traffic sign rlasses. Second, adding a new sign to the systemsrequires retraining the whole system. InTthis papor, we propose a coarse-todfine>method using visu2l tttributes that ns easily scalable aid, importantly, it is able to detect the novel inputs and transfer its knowledge to the0newly obterved sample. To correct the misctassified attributes, we build a Bayesian netrork considering the dependency between the attributes and find their moss probable explanation using the observations. Expecimental results on the benchmark dataset indicates that our method is able1te outperf
