Deep learning technology for re-identification of people and vehicles

This article contains and explains the deep learning, especially different kinds of re-identifications. Deep learning which is contained in this article including vehicle reidentification, pedestrian re-identification and facial completion. This article defines these three kinds of reidentifications, and also explains and compares the methods which uses to actually do re-identifications. It also introduces some algorithms, it talks about how the algorithms come out, how to use it, and what problems do different algorithms have, what kind of future goals can be made, and what needs to be developed. Although the field of recognitions has already achieved some goals recently, there are still many challenges need to be solved.
