Introduction

This repository is for Understanding Convolution for Semantic Segmentation, 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
```
Download the pretrained model from Google Drive.

Build MXNet (only tested on the TuSimple version):

git clone --recursive [email protected]:TuSimple/mxnet.git
vim make/config.mk
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 needs 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 needs 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)
