论文摘要
大多数研究人员使用基于分类的车辆重新识别。这始终需要对市场上的新车辆型号进行更新。在本文中,将提出两种类型的车辆重新识别。首先,标准方法需要搜索车辆的图像。 VRIC和VaheTID数据集适用于训练此模块。将详细解释如何使用训练有素的网络来提高此方法的性能,该网络是为分类而设计的。第二种方法将其作为输入的代表性图像,具有相似的品牌/型号,释放的年度和颜色。当搜索车的图像不可用时,这非常有用。它以输出形状和颜色特征而产生。匹配可以在数据库中使用,以重新识别与搜索车相似的车辆。为了获得重新识别的强大模块,已经培训了细粒度的分类,其类别由四个要素组成:车辆的制造是指车辆的制造商,例如梅赛德斯 - 奔驰(Mercedes-Benz),车辆的模型是指该制造商投资组合中的模型类型,例如C类,一年是指该模型的迭代,该模型可能会受到其制造商的逐步更改和升级的升级和车辆的视角。因此,所有四个元素都以提高特异性程度描述了车辆。车辆形状分类的目的是将这四个元素的组合分类。颜色分类已单独训练。将显示车辆重新识别的结果。使用开发的工具,将证明在视频图像和受控数据集上重新识别车辆。这项工作是根据赠款部分资助的。
Most of researchers use the vehicle re-identification based on classification. This always requires an update with the new vehicle models in the market. In this paper, two types of vehicle re-identification will be presented. First, the standard method, which needs an image from the search vehicle. VRIC and VehicleID data set are suitable for training this module. It will be explained in detail how to improve the performance of this method using a trained network, which is designed for the classification. The second method takes as input a representative image of the search vehicle with similar make/model, released year and colour. It is very useful when an image from the search vehicle is not available. It produces as output a shape and a colour features. This could be used by the matching across a database to re-identify vehicles, which look similar to the search vehicle. To get a robust module for the re-identification, a fine-grained classification has been trained, which its class consists of four elements: the make of a vehicle refers to the vehicle's manufacturer, e.g. Mercedes-Benz, the model of a vehicle refers to type of model within that manufacturer's portfolio, e.g. C Class, the year refers to the iteration of the model, which may receive progressive alterations and upgrades by its manufacturer and the perspective of the vehicle. Thus, all four elements describe the vehicle at increasing degree of specificity. The aim of the vehicle shape classification is to classify the combination of these four elements. The colour classification has been separately trained. The results of vehicle re-identification will be shown. Using a developed tool, the re-identification of vehicles on video images and on controlled data set will be demonstrated. This work was partially funded under the grant.
