LaST: Large-Scale Spatio-Temporal Person Re-identification

This repository contains the source code for loading the LaST dataset and evaluating its generalization.

Details

LaST is a large-scale dataset with more than 228k pedestrian images. It is used to study the scenario that pedestrians have a large activity scope and time span. Although collected from movies, we have selected suitable frames and labeled them as carefully as possible. Besides the identity label, we also labeled the clothes of pedestrians in the training set.

Train: 5000 identities and 71,248 images.
Val: 56 identities and 21,379 images.
Test: 5806 identities and 135,529 images.

Note: You can download LaST from these links: BaiduPan with password: vvfe. or Googledrive.

Prerequisites

Python 3.7
PyTorch 1.6
Torchvision 0.7.0
Cuda10.2

Experiments

Train LaST with BoT

python last_train_bot.py --train 1 --data_dir /data/last/ --logs_dir ./20210407_last_bot_base

Direct Transfer

Training Set	PRCC		Celeb-reID
	R1	mAP	R1	mAP
ImageNet	24.7%	13.5%	28.7%	3.0%
Market1501	29.0%	24.3%	36.7%	3.7%
DukeMTMC	28.3%	24.1%	40.9%	4.6%
MSMT17	26.2%	24.6%	43.4%	5.0%
LaST	39.3%	32.6%	47.0%	7.0%

Put the pre-trained model in the folder "pre_feat". For example, last_ini_imagenet.pth.

./pre_feat/last_ini_imagenet.pth

Modify the loaded model name as follows:

last_model_wts = torch.load(os.path.join('pre_feat', 'last_ini_imagenet.pth'))

Start Testing

python prcc_train_base_last.py --train 0 --data_dir /data/prcc/ --logs_dir ./pre_feat
