Vehicle Re-Identification in Multi-Camera scenarios based on Ensembling Deep Learning Features

Paula Moral, Álvaro García-Martín, José M. Martínez

Abstract: Vehicle re-identification (ReID) across multiple cameras is one of the principal issues in Intelligent Transportation System (ITS). The main challenge that vehicle ReID presents is the large intra-class and small inter-class variability of vehicles appearance, followed by illumination changes, different viewpoints and scales, lack of labelled data and camera resolution. To address these problems, we present a vehicle ReID system that combines different ReID models, including appearance and orientation deep learning features. Additionally, for results refinement re-ranking and a post-processing step taking into account the vehicle trajectory information provided by the CityFlow-ReID dataset are applied.
