Update

We extend AlignPS by augmenting it with an ROI-Align head, which further improves the performance. Details can be found here.

Introduction

This is the implementation for Anchor-Free Person Search in CVPR2021 and its extended version Efficient Person Search: An Anchor-Free Approach.

Installation

This project is developed upon MMdetection, please refer to install.md to install MMdetection.

We utilized mmcv=1.1.5, pytorch=1.7.0

Dataset

Download CUHK-SYSU and PRW.

We provide coco-style annotation in demo/anno.

For CUHK-SYSU, change the path of your dataset and the annotaion file in the config file L3, L38, L43, L48

For PRW, change the paths in these config files: config1 config2

Experiments

1. Train

sh run_train.sh

2. Test CUHK-SYSU

Change the paths in L59 and L72 in test_results.py

sh run_test.sh

For ROI-AlignPS, change the paths in test_results_psd.py

sh run_test_roi.sh

3. Test PRW

Change the paths in L127 and L128 in test_results_prw.py

sh run_test_prw.sh

For ROI-AlignPS, change the paths in test_results_psd_prw.py

sh run_test_roi_prw.sh
