Unsupervised Pre-training for Person Re-identification (LUPerson).

PWC PWC PWC PWC

The repository is for our CVPR2021 paper Unsupervised Pre-training for Person Re-identification.

LUPerson Dataset

LUPerson is currently the largest unlabeled dataset for Person Re-identification, which is used for Unsupervised Pre-training. LUPerson consists of 4M images of over 200K identities and covers a much diverse range of capturing environments.

Details can be found at ./LUP.

Pre-trained Models

Finetuned Results

For MGN with ResNet50:

Dataset mAP cmc1 path
MSMT17 66.06/79.93 85.08/87.63 MSMT
DukeMTMC 82.27/91.70 90.35/92.82 Duke

CUHK03-L 74.54/85.84 74.64/82.86 CUHK03

These numbers are a little different from those reported in our paper, and most are slightly better.

For MGN with ResNet101:

Dataset mAP cmc1 path
MSMT17 68.41/81.12 86.28/88.27 -
