Traffic Sign Recognition Based on the YOLOv3 Algorithm by Chunpeng Gong, Aijuan Li, Yumin Song, Ning Xu, Weikai He

“…Furthermore, the bounding box regression is more stable when the distance-IoU (DIoU) loss is used, which takes into account the distance between the target and anchor, the overlap rate, and the scale. The Tsinghua–Tencent 100K (TT100K) traffic sign dataset’s 12 anchors are recalculated using the K-means clustering algorithm, while the dataset is balanced and expanded to address the problem of an uneven number of target classes in the TT100K dataset. …”
