- Implementaion based on Harmonic DenseNet: A low memory traffic network (ICCV 2019)
- Refer to Pytorch-HarDNet for more information about the backbone model
- This repo was forked from meetshah1995/pytorch-semseg
- Simple U-shaped encoder-decoder structure
- Conv3x3/Conv1x1 only (including the first layer)
- No self-attention layer or Pyramid Pooling

Setup config file
Please see the usage section in meetshah1995/pytorch-semseg
To train the model :
python train.py [-h] [--config [CONFIG]]
--config Configuration file to use (default: hardnet.yml)
To validate the model :
usage: validate.py [-h] [--config [CONFIG]] [--model_path [MODEL_PATH]] [--save_image]
[--eval_flip] [--measure_time]
--config Config file to be used
--model_path Path to the saved model
--eval_flip Enable evaluation with flipped image | False by default
--measure_time Enable evaluation with time (fps) measurement | True by default
--save_image Enable writing result images to out_rgb (pred label blended images) and out_predID
