Bias Eliminate Domain Adaptive Pedestrian Re-identification [Technique Report]
This repo contains our code for VisDA2020 challenge at ECCV workshop.
Introduction
This work mainly solve the domain adaptive pedestrian re-identification problem by eliminishing the bias from inter-domain gap and intra-domain camera difference.
This project is mainly based on reid-strong-baseline.
Get Started
- Clone the repo
git clone https://github.com/vimar-gu/Bias-Eliminate-DA-ReID.git - Install dependencies:
- pytorch >= 1.0.0
- python >= 3.5
- torchvision
- yacs
- Prepare dataset. It can be obtained from Simon4Yan/VisDA2020.
- We use ResNet-ibn and HRNet as backbones. ImageNet pretrained models can be downloaded in here and here.

Some tips
- By our experience, there can be a large fluctuation of validation scores which are not completely positive correlated to the scores on testing set.
- We have fixed the random seed in the updates. But there might still be some difference due to environment.
- Multiple camera models in the testing phase may boost the performance by a little bit.
