deepmask-pytorch

This repository contains a PyTorch re-implementation for the DeepMask and SharpMask object proposal algorithms.

Requirements and Dependencies

  • Linux
  • NVIDIA GPU with compute capability 3.5+
  • python3
  • PyTorch 0.4.1

Quick Start

To run pretrained DeepMask models to generate object proposals, follow these steps:

  1. Clone this repository into $DEEPMASK:

    git clone https://github.com/foolwood/deepmask-pytorch.git
cd deepmask-pytorch
DEEPMASK=$PWD
export PYTHONPATH=$DEEPMASK:$PYTHONPATH

  2. Download pre-trained DeepMask models:

    mkdir -p $DEEPMASK/pretrained/deepmask; cd $DEEPMASK/pretrained/deepmask
wget http://www.robots.ox.ac.uk/~qwang/DeepMask.pth.tar

  3. Run computeProposals.py with a given model and optional target image (specified via the -img option):

    # apply to a default sample image (data/testImage.jpg)
cd $DEEPMASK
python tools/computeProposals.py --arch DeepMask --resume $DEEPMASK/pretrained/deepmask/DeepMask.pth.tar --img ./data/test.jpg

Training Your Own Model

To train your own DeepMask models, follow these steps:

Preparation

  1. If you have not done so already, clone this repository into $DEEPMASK:

    git clone https://github.com/foolwood/deepmask-pytorch.git
cd deepmask-pytorch
DEEPMASK=$PWD
export PYTHONPATH=$DEEPMASK:$PYTHONPATH

  2. Download and extract the COCO images and annotations:

    mkdir -p $DEEPMASK/data/coco; cd $DEEPMASK/data/coco
wget http://images.cocodataset.org/zips/train2017.zip
wget http://images.cocodataset.org/zips/val2017.zip
wget http://images.cocodataset.org/annotations/annotations_trainval2017.zip

unzip ./train2017.zip && unzip ./val2017.zip && unzip ./annotations_trainval2017.zip
cd $DEEPMASK/loader/pycocotools && make

Training

To train DeepMask, launch the train.py script. It contains several options, to list them, simply use the --help flag.

cd $DEEPMASK
CUDA_VISIBLE_DEVICES=0,1,2,3 python tools/train.py --dataset coco -j 20 --freeze_bn
CUDA_VISIBLE_DEVICES=0,1,2,3 python tools/train.py --dataset coco -j 20 --arch SharpMask --freeze_bn

Testing

Test on COCO validation set (5K).

sh scripts/test_recall_coco.sh
