Highlights

---

• Domain Adaptive Mixing Mechanism: Our approach introduces a diligent domain adaptive mixing mechanism with the aim of narrowing the gap between the source and target domains within the context of person search domain adaptation. Specifically, we train mixed domain representations that effectively bridge the differences between these two domains, expediting the transfer of source information to the target domain. This, in turn, enhances the performance of unsupervised domain adaptation (UDA) in person search tasks.
• Bridge and Disparity Losses: To boost our domain adaptation capabilities and create refined mixed domain representations, we introduce two bridge losses along with a disparity loss.
• Decoupling of the NAE: In order to mitigate the conflicts between detection and ReID (Re-identification) and further enhance domain adaptation, we propose the decoupling of the NAE representation.
• Performance Comparison: Experimental results clearly illustrate the promising performance of our method on two datasets, surpassing the capabilities of state-of-the-art methods. These results underscore the effectiveness of our approach.

Framework

Performance :

Source	Target	mAP	Top-1	CKPT
PRW	CUHK-SYSU	79.5	81.3	ckpt
CUHK-SYSU	PRW	36.7	81.2	ckpt

Installation

run python setup.py develop to enable SPCL

Install Nvidia Apex

Run pip install -r requirements.txt in the root directory of the project.

Data Preparation

1. Download CUHK-SYSU and PRW datasets, and unzip them.
2. Or can be found at PS Datasets
3. Modify configs/prw_da.yaml and configs/cuhk_sysu_da.yaml to change the dataset store place to your own path.

Testing

1. Following the link in the above table, download our pretrained model to anywhere you like

2. Evaluate its performance by specifying the paths of checkpoint and corresponding configuration file.

PRW as the target domain:

python train_da_dy_cluster.py --cfg configs/cuhk_sysu_da.yaml --eval --ckpt $MODEL_PATH

CUHK-SYSU as the target domain:

python train_da_dy_cluster.py --cfg configs/prw_da.yaml --eval --ckpt $MODEL_PATH

Training

PRW as the target domain:

python train_da_dy_cluster.py --cfg configs/cuhk_sysu_da.yaml

CUHK-SYSU as the target domain:

python train_da_dy_cluster.py --cfg configs/prw_da.yaml
