🏃 Train

1️⃣ Data Prearation

• Train Dataset

🔸 Download the train dataset and put them(atrw_reid_train, atrw_anno_reid_train) into the {repo_root}/process_data/.

🔸 Transform the data style for the model

python data_process.py

2️⃣ Pre-trained weight

🔸 Creat a new folder named /pretrained_model/ under the {repo_root}/:

cd data
mkdir pretrained_model

🔸 Download the pre-trained weighte and put them into the {repo_root}/pretrained_model/.

• ResNet50

• ResNet101

• ResNet18

• ResNet34

• ResNet152

• SEResNet50

• SEResNet101

• ResNeXt50

• ResNeXt101

• SEResNeXt50

• SEResNeXt101

And make sure the repo files as the following structure:

{repo_root}

 ├── configs
 ├── data
 |   ├── AmurTiger
 │   │   ├── flod0
 │   │   └── flod1

👏 Train Now!

In this competition, I use 4-fold to train and ues the Resnet152 for the backbone.

python train.py --config_file ./configs/tiger_b_resnet152_34.yml --index_flod 0

python train.py --config_file ./configs/tiger_b_resnet152_34.yml --index_flod 1

python train.py --config_file ./configs/tiger_b_resnet152_34.yml --index_flod 2

python train.py --config_file ./configs/tiger_b_resnet152_34.yml --index_flod 3

Eventually the trained model will be saved in {repo_root}/tiger_out/b_resnet152_34/

🏃 Inference

1️⃣ Data Preparation

🔸 Creat a new folder named /reid_test/ under the {repo_root}/data/AmurTiger/:

cd data
cd AmurTiger
mkdir reid_test

🔸 Put the test images in the {repo_root}/data/AmurTiger/reid_test/.

2️⃣ Download Pretrained Model

The trained weights are following:

• Trained weight

Download it and create a new folder under the {repo_root} named /trained_weight/

mkdir trained_weight

Unzip the model.zip(there will be 8 trained weights) and put them in the {repo_root}/trained_weight/.

And make sure the repo files as the following structure:

  {repo_root}
  ├── config
  ├── configs

👏 Inference Now!

python demo.py

This process will take about 6 minutes, just a moment, please.

It will generate a submission in the {repo_root/}:

• submission_plain.json —-you can submit to the Tiger Plain Re-ID track.

👉 Section2  The Tiger Wild Re-ID

🏃 Train

Same thing up here

🏃 Inference

In this task, it's a two-step process: Detection and Re-id

1️⃣ Detection

🔸 Please follow this repo: CWCV2019-Amur-Tiger-Detection

Note that the two repos depend on different environments(Re-ID is pytorch==1.0.1, Detection is pytorch==0.4.1)

🔸 Run scrip in above repo will generate 3 files in the {repo_root/}:

• det_submission.json

• wide_box.json

• reid_test(a folder) --it contains images that have been detected and croped.

This wide_box.json and reid_test(a folder) are what we need next.

2️⃣ Re-ID

Use this reop.

🔸 Data Preparation

Put wide_box.json and reid_test(a folder)(created by the detector above) under the {repo_root}/data/AmurTiger/.

🔸 Download Pretrained Model(Same as the plain re-id)

The trained weight is following:

• Trained weight

Download it and create a new folder under the {repo_root} named /trained_weight/

mkdir trained_weight

Unzip the model.zip and put them into the {repo_root}/trained_weight/.

And make sure the repo files as the following structure:
