Self-supervised Structure-sensitive Learning (SSL)

Ke Gong, Xiaodan Liang, Xiaohui Shen, Liang Lin, "Look into Person: Self-supervised Structure-sensitive Learning and A New Benchmark for Human Parsing", CVPR 2017.

Introduction

SSL is a state-of-the-art deep learning methord for human parsing built on top of Caffe. This novel self-supervised structure-sensitive learning approach can impose human pose structures into parsing results without resorting to extra supervision (i.e., no need for specifically labeling human joints in model training). The self-supervised learning framework can be injected into any advanced neural networks to help incorporate rich high-level knowledge regarding human joints from a global perspective and improve the parsing results.

This distribution provides a publicly available implementation for the key model ingredients reported in our latest paper which is accepted by CVPR2017.

We newly introduce a novel Joint Human Parsing and Pose Estimation Network (JPPNet), which is accepted by T-PAMI 2018. (Paper and Code)

Look into People (LIP) Dataset

The SSL is trained and evaluated on our LIP dataset for 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 with best performance at google drive and baidu drive.

Train and test

  1. Download LIP dataset or prepare your own data.
  2. Put the images(.jpg) and segmentations(.png) into ssl/human/data/images and ssl/human/data/labels
  3. Put the train, val, test lists into ssl/human/list. Each type contains a list for path and a list for id (e.g., train.txt and train_id.txt)
  4. Download the pre-trained model and put it into ssl/human/model/attention/. You can also refer DeepLab for more models.
  5. Set up your init.caffemodel before training and test.caffemodel before testing. You can simply use a soft link.
  6. The prototxt files for network config are saved in ssl/human/config
  7. In run_human.sh, you can set the value of RUN_TRAIN adn RUN_TEST to train or test the model.
  8. After you run TEST, the computed features will be saved in ssl/human/features. You can run the provided MATLAB script, show.m to generate visualizable results. Then you can run the Python script, test_human.py to evaluate the performance.
