Research on person re-identification based on deep learning

With the development of deep learning, researchers began to explore the application of deep learning to person reidentification tasks and proposed a large number of methods, which also ushered in new challenges. In order to facilitate scholars to systematically understand the research status and development trends in this field, this paper firstly introduced the person reidentification task and existing problems. Secondly, according to training methods, it discussed the research progress of the supervised learning, semi-supervised learning/weak supervision learning and unsupervised learning for the person re-identification task. It introduced the application of GAN(generative adversarial networks) and attention mechanism in person re-identification following recent research hotspots. After that, it enumerated some commonly used data sets(Market-1501, CUHK03, etc. ) and their performance in this field. Finally, this paper looked forward to the future research direction of person re-identification.
