# UnrealPerson: An Adaptive Pipeline for Costless Person Re-identification
In our paper ([arxiv](https://arxiv.org/abs/2012.04268v2)), we propose a novel pipeline, UnrealPerson, that decreases the costs in both the training and deployment stages of person ReID.

We develop an automatic data synthesis toolkit and use synthesized data in mutiple ReID tasks, including (i) Direct transfer, (ii) Unsupervised domain adaptation, and (iii) Supervised fine-tuning.

**This repo contains:**
1. The **synthesized data** we use in the paper, including more than 6,000 identities in 4 different virtual scenes. Please see this document [Download.md](Download.md) for details.
2. The codes for our experiments reported in the paper. To reproduce the results on direct transfer, supervised learning and unsupervised domain adaptation, please refer to this document: [Experiments.md](Experiments.md) .
3. The necessary scripts and detailed tutorials to help you generate your own data. [SynthesisToolkit.md](SynthesisToolkit.md)

## Demonstration

**Highlights:**
1. In direct transfer evaluation, we achieve 38.5% rank-1 accuracy on MSMT17 and 79.0% on Market-1501 using our unreal data.
2. In unsupervised domain adaptation, we achieve 68.2% rank-1 accuracy on MSMT17 and 93.0% on Market-1501 using our unreal data.
3. We obtain a better pre-trained ReID model with our unreal data.
