Introduction

We propose a Dual Attention Network (DANet) to adaptively integrate local features with their global dependencies based on the self-attention mechanism. And we achieve new state-of-the-art segmentation performance on three challenging scene segmentation datasets, i.e., Cityscapes, PASCAL Context and COCO Stuff-10k dataset.

Cityscapes testing set result

We train our DANet-101 with only fine annotated data and submit our test results to the official evaluation server.

Updates

2020/9：Renew the code, which supports Pytorch 1.4.0 or later!

2020/8：The new TNNLS version DRANet achieves 82.9% on Cityscapes test set (submit the result on August, 2019), which is a new state-of-the-arts performance with only using fine annotated dataset and Resnet-101. The code will be released in DRANet.

2020/7：DANet is supported on MMSegmentation, in which DANet achieves 80.47% with single scale testing and 82.02% with multi-scale testing on Cityscapes val set.

2018/9：DANet released. The trained model with ResNet101 achieves 81.5% on Cityscapes test set.

Usage

1. Install pytorch

   • The code is tested on python3.6 and torch 1.4.0.
   • The code is modified from PyTorch-Encoding.

2. Clone the resposity

   git clone https://github.com/junfu1115/DANet.git 
   cd DANet 
   python setup.py install

3. Dataset

   • Download the Cityscapes dataset and convert the dataset to 19 categories.
   • Please put dataset in folder ./datasets

4. Evaluation for DANet

   • Download trained model DANet101 and put it in folder ./experiments/segmentation/models/

   • cd ./experiments/segmentation/

   • For single scale testing, please run:

   • CUDA_VISIBLE_DEVICES=0,1,2,3 python test.py --dataset citys --model danet --backbone resnet101 --resume  models/DANet101.pth.tar --eval --base-size 2048 --crop-size 768 --workers 1 --multi-grid --multi-dilation 4 8 16 --os 8 --aux --no-deepstem

   • Evaluation Result

     The expected scores will show as follows: DANet101 on cityscapes val set (mIoU/pAcc): 79.93/95.97(ss)

5. Evaluation for DRANet

   • Download trained model DRANet101 and put it in folder ./experiments/segmentation/models/

   • Evaluation code is in folder ./experiments/segmentation/

   • cd ./experiments/segmentation/

   • For single scale testing, please run:

   • CUDA_VISIBLE_DEVICES=0,1,2,3 python test.py --dataset citys --model dran --backbone resnet101 --resume  models/dran101.pth.tar --eval --base-size 2048 --crop-size 768 --workers 1 --multi-grid --multi-dilation 4 8 16 --os 8 --aux

   • Evaluation Result

     The expected scores will show as follows: DRANet101 on cityscapes val set (mIoU/pAcc): 81.63/96.62 (ss)
