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
