LUPerson

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

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
Market1501	91.12/96.16	96.26/97.12	Market
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	-
DukeMTMC	84.15/92.77	91.88/93.99	-
Market1501	91.86/96.21	96.56/97.03	-
CUHK03-L	75.98/86.73	75.86/84.07	-

The numbers are in the format of without RR/with RR.
