Comprehensive Attention Self-Distillation for Weakly-Supervised Object Detection

Update(May 30): Please use the latest parallelized version(May30 branch;24G GPU required). The VOC07 is around 57.00% mAP(slightly better than reported and download the model below). For 12G GPU users, please use the master branch(Some functions are cut down to save memory).

This is the official implementation of:

Zeyi Huang', Yang Zou', Vijayakumar Bhagavatula, and Dong Huang, Comprehensive Attention Self-Distillation for Weakly-Supervised Object Detection, NeurIPS 2020, Arxiv version.

Installation

Requirements

Python == 3.7
Pytorch == 1.1.0
Torchvision == 0.3.0
Cuda == 10.0
cython
scipy
sklearn
opencv
GPU: TITAN RTX (24G of memory)

Note: To train with GPU of small memory, CASD_IW is partially parallelized. Fully parallelized version is coming soon. Thanks for your patience.

Preparation

Clone the repository

git clone https://github.com/DeLightCMU/CASD.git

Compile the CUDA code

cd CASD/lib
bash make_cuda.sh

Download the training, validation, test data and the VOCdevkit

mkdir data
cd data/
wget http://host.robots.ox.ac.uk/pascal/VOC/voc2007/VOCtrainval_06-Nov-2007.tar
wget http://host.robots.ox.ac.uk/pascal/VOC/voc2007/VOCtest_06-Nov-2007.tar
wget http://host.robots.ox.ac.uk/pascal/VOC/voc2012/VOCdevkit_18-May-2011.tar

Extract all of these tars into one directory named VOCdevkit

tar xvf VOCtrainval_06-Nov-2007.tar
tar xvf VOCtest_06-Nov-2007.tar
tar xvf VOCdevkit_08-Jun-2007.tar

Create symlinks for PASCAL VOC dataset

cd CASD/data
ln -s VOCdevkit VOCdevkit2007

Download pretrained ImageNet weights from here, and put it in the data/imagenet_weights/
Download selective search proposals from here, and put it in the data/selective_search_data/

Training and Testing

Train a vgg16 Network on VOC 2007 trainval

bash experiments/scripts/train_faster_rcnn.sh 0 pascal_voc vgg16

Test a vgg16 Network on VOC 2007 test
