Weakly-supervised Pedestrian Attribute Localization Network (WPAL-network) is a Convolutional Neural Network (CNN) structure designed for recognizing attributes from objects as well as localizing them. Currently it is developed to recognize attributes from pedestrians only, using the Richly Annotated Pedestrian (RAP) database or PETA database.

Installation

1. Clone this repository

   # Make sure to clone with --recursive
   git clone --recursive https://github.com/kyu-sz/Weakly-supervised-Pedestrian-Attribute-Localization-Network.git

2. Build Caffe and pycaffe

   This project use python layers for input, etc. When building Caffe, set the WITH_PYTHON_LAYER option to true.

   WITH_PYTHON_LAYER=1 make all pycaffe -j 8

3. Download the RAP database

   To get the Richly Annotated Pedestrian (RAP) database, please visit rap.idealtest.org to learn about how to download a copy of it.

   It should have two zip files.

   $RAP/RAP_annotation.zip
   $RAP/RAP_dataset.zip
   

4. Unzip them both to the directory.

   cd $RAP
   unzip RAP_annotation.zip
   unzip RAP_dataset.zip

5. Create symlinks for the RAP database

   cd $WPAL_NET_ROOT/data/dataset/
   ln -s $RAP RAP

Usage

To train the model, first fetch a pretrained VGG_CNN_S model by:

./data/scripts/fetch_pretrained_vgg_cnn_s_model.sh

Then run experiment script for training:

./experiments/examples/VGG_CNN_S/train_vgg_s_rap_0.sh

Experiment script for testing is also available:

./experiments/examples/VGG_CNN_S/test_vgg_s_rap.sh
