摘要:

了解其他交通是自动驾驶汽车在现实世界中运行的先决条件。在本文中,我们展示了如何使用目标检测CNN的内在特征图来唯一地识别来自仪表盘摄像头的车辆。使用预先训练的“YOLO”网络的特征图从来自高分辨率数据集的35辆车的20个不同图像中创建700个深度集成特征签名(DIFS),并从来自较低分辨率跟踪基准数据集的17辆车的20个不同图像中创建340个签名。YOLO网络被训练用于对一般对象类别进行分类,例如将检测到的对象分类为“汽车”或“卡车”。5-折叠最近邻(1NN)分类用于从网络中间层的特征图创建的DIFS上,以正确地识别独特的车辆,对于高分辨率数据的识别率为96.7%,对于低分辨率数据的识别率为86.8%。我们的结论是,通过创建深度集成特征签名(DIFS),经过训练以区分不同类别的深度神经检测网络可以成功地用于识别属于同一类别的不同实例。

英文摘要:

Being aware of other traffic is a prerequisite for self-driving cars to operate in the real world. In this paper, we show how the intrinsic feature maps of an object detection CNN can be used to uniquely identify vehicles from a dash-cam feed. Feature maps of a pretrained `YOLO' network are used to create 700 deep integrated feature signatures (DIFS) from 20 different images of 35 vehicles from a high resolution dataset and 340 signatures from 20 different images of 17 vehicles of a lower resolution tracking benchmark dataset. The YOLO network was trained to classify general object categories, e.g. classify a detected object as a `car' or `truck'. 5-Fold nearest neighbor (1NN) classification was used on DIFS created from feature maps in the middle layers of the network to correctly identify unique vehicles at a rate of 96.7\% for the high resolution data and with a rate of 86.8\% for the lower resolution data. We conclude that a deep neural detection network trained to distinguish between different classes can be successfully used to identify different instances belonging to the same class, through the creation of deep integrated feature signatures (DIFS).
