摘要:
Person re-identification aims to associate the same person across different views and can be taken as a subproblem of image retrieval. It has extensive application prospects in many areas such as intelligent video surveillance, security, and criminal investigation. Due to poor illumination condition, image resolution, camera viewpoint, environment, and pedestrian pose, person re-identification has become one of the challenging problems in computer vision. Early person re-identification methods mostly rely on hand-crafted features and researches are conducted on small-scale datasets. In recent years, the emergence of large-scale datasets and rapid development of deep learning techniques provide person re-identification with new opportunities. This survey gives a detailed overview of the history, state of the art, and typical methods in this domain. Firstly, the general framework of person re-identification is presented. Then, feature representation, similarity measurement, and two key aspects of person re-identification, are further summarized, respectively. We also highlight the application of rapid developing deep learning techniques to person re-identification. Moreover, the representative datasets of person re-identification and methods of obtaining excellent performance on each dataset are analyzed and compared. Finally, the future trends of this field are discussed. Copyright © 2018 Acta Automatica Sinica. All rights reserved.
