Introduction

PGN is a state-of-art deep learning methord for semantic part segmentation, instance-aware edge detection and instance-level human parsing built on top of Tensorflow.

This distribution provides a publicly available implementation for the key model ingredients reported in our latest paper which is accepted by ECCV 2018.

Crowd Instance-level Human Parsing (CIHP) Dataset

The PGN is trained and evaluated on our CIHP dataset for isntance-level human parsing. Please check it for more model details. The dataset is also available at google drive and baidu drive.

Pre-trained models

We have released our trained models of PGN on CIHP dataset at google drive.

Inference

1. Download the pre-trained model and store in $HOME/checkpoint.
2. Prepare the images and store in $HOME/datasets.
3. Run test_pgn.py.
4. The results are saved in $HOME/output
5. Evaluation scripts are in $HOME/evaluation. Copy the groundtruth files (in _Instanceids folder) into $HOME/evaluation/Instance_part_val before you run the script.

Training

1. Download the pre-trained model and store in $HOME/checkpoint.
2. Download CIHP dataset or prepare your own data and store in $HOME/datasets.
3. For CIHP dataset, you need to generate the edge labels and left-right flipping labels (optional). We have provided a script for reference.
4. Run train_pgn.py to train PGN.
5. Use test_pgn.py to generate the results with the trained models.
6. The instance tool is used for instance partition process from semantic part segmentation maps and instance-aware edge maps, which is written in MATLAB.
