This repository is based on:

1. https://github.com/HRNet/HRNet-Semantic-Segmentation, the official code of high-resolution representations for Semantic Segmentation.
2. https://github.com/HRNet/Lite-HRNet, the official code of [Lite-HRNet: A Lightweight High-Resolution Network] (https://arxiv.org/abs/2104.06403).
3. https://github.com/shachoi/HANet, the official code of [Cars Can't Fly Up in the Sky: Improving Urban-Scene Segmentation via Height-Driven Attention Networks] (https://arxiv.org/abs/2003.05128)

1. Clone this repository and install the dependencies: pip install -r requirements.txt

All the models files can be found in lib/models. The default file of HRNet model is lib/models/seg_hrnet.py.

For adding the HANet, we modified the default file lib/models/seg_hrnt_hanet.py, and we added the following files:

1. lib/models/deepv3.py.
2. lib/models/HANet.py.
3. lib/models/PosEmbedding_HANet.py.
4. lib/models/mynn_HANet.py.

For lite-HRNet, we added the following files:

1. lib/models/litehrnet.py.
2. lib/core/resnet.py.

1. Specify the training script in tools/. a. For trainig the (hrnet) models use the tools/train.py. b. For trainig the (lite-hrnet) models use the tools/lite-train.py.
2. Specify the configuration file (.yaml) of the experiment in experiments/cityscapes.

Here are some examples scripts to start training:

Training HRNet-W32 on Cityscapes with a batch size of 8:

python tools/train.py --cfg experiments/cityscapes/seg_hrnet_w32.yaml

Training Lite-HRNet-W32 on Cityscapes with a batch size of 8:

python tools/lite_train.py --cfg experiments/cityscapes/seg_lite_hrnet_w32.yaml

We adopt sync-bn implemented by InplaceABN for PyTorch 0.4.1 experiments and the official sync-bn provided by PyTorch for PyTorch 1.10 experiments.

We adopt data precosessing on the PASCAL-Context dataset, implemented by PASCAL API.
