Query: Object Detection in Specific Traffic Scenes using YOLOv2   object detection framework plays crucial role in autonomous driving. In this
paper, we introduce the real-time object detection framework called You Only
Look Once (YOLOv1) and the related improvements of YOLOv2. We further explore
the capability of YOLOv2 by implementing its pre-trained model to do the object
detecting tasks in some specific traffic scenes. The four artificially designed
traffic scenes include single-car, single-person, frontperson-rearcar and
frontcar-rearperson.
