TuSimple-DUC
by Panqu Wang, Pengfei Chen, Ye Yuan, Ding Liu, Zehua Huang, Xiaodi Hou, and Garrison Cottrell.
Introduction
This repository is for Understanding Convolution for Semantic Segmentation (WACV 2018), which achieved state-of-the-art result on the CityScapes, PASCAL VOC 2012, and Kitti Road benchmark.
Requirement
We tested our code on:
Ubuntu 16.04, Python 2.7 with
MXNet (0.11.0), numpy(1.13.1), cv2(3.2.0), PIL(4.2.1), and cython(0.25.2)
Usage
-
Clone the repository:
git clone git@github.com:TuSimple/TuSimple-DUC.git python setup.py develop --user
-
Download the pretrained model from Google Drive.
-
Build MXNet (only tested on the TuSimple version):
git clone --recursive git@github.com:TuSimple/mxnet.git vim make/config.mk (we should have USE_CUDA = 1, modify USE_CUDA_PATH, and have USE_CUDNN = 1 to enable GPU usage.) make -j cd python python setup.py develop --user
For more MXNet tutorials, please refer to the official documentation.
-
Training:
cd train python train_model.py ../configs/train/train_cityscapes.cfg
The paths/dirs in the
.cfg
file need to be specified by the user. -
Testing
cd test python predict_full_image.py ../configs/test/test_full_image.cfg
The paths/dirs in the
.cfg
file need to be specified by the user. -
Results:
Modify the
result_dir
path in the config file to save the label map and visualizations. The expected scores are:(single scale testing denotes as 'ss' and multiple scale testing denotes as 'ms')
- ResNet101-DUC-HDC on CityScapes testset (mIoU): 79.1(ss) / 80.1(ms)
- ResNet152-DUC on VOC2012 (mIoU): 83.1(ss)
