Multi-direction and Multi-scale Pyramid in Transformer for Video-based Pedestrian Retrieval on PolarbearVidID

LICENSE Python pytorch PWC PWC

Implementation of the proposed PiT used on the PolarBearVidID Dataset. Please refer to [PolarBearVidID @ MDPI] and [PiT @ Arxiv].

dataset framework

Getting Started

Requirements

Here is a brief instruction for installing the experimental environment.

# Windows 10 and 11 (use cmd)
# install conda (add to path)
$ conda create -n PiT python=3.6 -y
$ conda activate PiT (Win 11: activate PiT)
# install pytorch 1.8.1/1.6.0 (other versions may also work)
$ pip install torch==1.8.1+cu111 torchvision==0.9.1+cu111 torchaudio==0.8.1 -f https://download.pytorch.org/whl/torch_stable.html
$ pip install timm scipy einops yacs opencv-python==4.3.0.36 tensorboard pandas

Download pre-trained model

The pre-trained vit model can be downloaded in this link and should be put in the checkpoints/ directory.

Dataset Preparation

Download PolarBearVidID Dataset at PolarBearVidID and store it in the data/PolarBearVidID Directory.

Training and Testing

# This command below includes the training and testing processes.
$ python train.py --config_file configs/PolarBearVidID/pit.yml MODEL.DEVICE_ID "('0')"

Visualize findings

$ tensorboard --logdir_spec fold1:logs\PolarBearVidID_PiT\1,fold2:logs\PolarBearVidID_PiT\2,fold3:logs\PolarBearVidID_PiT\3,fold4:logs\PolarBearVidID_PiT\4,fold5:logs\PolarBearVidID_PiT\5

Create attention map

$ python vis.py --config_file configs/PolarBearVidID/pit.yml MODEL.DEVICE_ID "('0')"

Results on PolarBearVidID

With a rank-1 performance of 95.88 ± 1.45 % and a mAP score of 81.62 ± 7.23 %, the adapted PiT_14p trained for 400 epochs outperformed the image-based baseline approach while almost reaching the performance of GLTR.
