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

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

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.

LUPerson can only be used for research, commercial usage is forbidden.

Details can be found at ./LUP.

For MGN with ResNet50:

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

For MGN with ResNet101:

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

We extend our LUPerson to LUPerson-NL with Noisy Labels which are generated from tracking algorithm, Please check for our CVPR22 paper Large-Scale Pre-training for Person Re-identification with Noisy Labels. And LUPerson-NL dataset is available at https://github.com/DengpanFu/LUPerson-NL

LUPerson and LUPerson-NL are used by some work and have obtained very good performance.
