Data preparation

1. Download CUHK-PEDES dataset and save it anywhere you like (e.g. ~/datasets/cuhkpedes/).
2. Download text_attribute_graph (GoogleDrive / BaiduYun(code: vbss)) which are the text phrases parsed from the sentences, and save it in (e.g. ~/datasets/cuhkpedes/).
3. Use the provided Human Parsing Network to generate the attribute segmentations, and save it in (e.g. ~/datasets/cuhkpedes/).
4. Run the script in tools/cuhkpedes/convert_to_json to generate the json files as annotations.

python tools/cuhkpedes/convert_to_json.py --datadir ~/datasets/cuhkpedes/ --outdir datasets/cuhkpedes/annotations

Your datasets directory should look like this:

ViTAA
-- configs
-- tools
-- vitaa
-- datasets
   |-- cuhkpedes
   |   |-- annotations
   |   |   |-- test.json
   |   |   |-- train.json
   |   |   |-- val.json
   |   |-- imgs
   |   |   |-- cam_a
   |   |   |-- cam_b
   |   |   |--  ...
   |   |-- segs
   |   |   |-- cam_a
   |   |   |-- cam_b
   |   |   |--  ...

Training

# single-gpu training
python tools/train_net.py --config-file configs/cuhkpedes/bilstm_r50_seg.yaml

# multi-gpu training
We provide the code for distributed training but they haven't been tested

Note: We train ViTAA with batch_size=64 on one Tesla V100 GPU. If your GPU doesn't support such batch size, please follow the Linear Scaling Rule to adjust the configuration.

Testing

# single-gpu testing
python tools/test.py --config-file configs/cuhkpedes/bilstm_r50_seg.yaml --checkpoint-file output/cuhkpedes/...

Human Parsing Network

We separately provide the code of our Human Parsing Network because we think it might be a useful tool for the community.

Acknowledgement

Our codes is based on maskrcnn-benchmark, great thanks to their work.
