AICity-reID 2020 (track2)

In this repo, we include the 1st Place submission to AICity Challenge 2020 re-id track (Baidu-UTS submission)

[Paper] [Video]

We fuse the models trained on Paddlepaddle and Pytorch. To illustrate them, we provide the two training parts seperatively as following.

Performance：

AICITY2020 Challange Track2 Leaderboard

TeamName mAP Link
Baidu-UTS(Ours) 84.1% code
RuiYanAI 78.1% code
DMT 73.1% code

Trained Models

How to extract features? Please refer to [Here] and there is one simplified version at [Here]. Here we provide one model of the final models.

  • SE_imbalance_s1_384_p0.5_lr2_mt_d0_b24+v+aug (AICity 2020) can be downloaded at [GoogleDrive].

The state-of-the-art model achieving 83.41% mAP on VeRi-776, which is based on our TMM paper.

  • Training on VehicelNet only (80.91): Res50_imbalance_s1_256_p0.5_lr2_mt_d0_b48 (TMM) can be downloaded at [GoogleDrive].
  • Finetuning on VeRi (83.41): ft_Res50_imbalance_s1_256_p0.5_lr1_mt_d0.2_b48_w5 (TMM) can be downloaded at [GoogleDrive].

Extracted Features & Camera Prediction & Direction Prediction:

I have updated the feature. You may download from GoogleDrive or OneDrive (expired by July 1 2022)
