Ubuntu            16.04
Python            3.8.10
Tensorflow-gpu    2.5.0
CUDA              11.2

1. Download HCI Light field dataset from https://hci-lightfield.iwr.uni-heidelberg.de/.
2. Unzip the LF dataset and move 'additional/, training/, test/, stratified/ ' into the 'hci_dataset/'.
3. Stage 1: Run python train_sub.py

• Checkpoint files will be saved in 'LF_checkpoints/XXX_ckp/iterXXXX_valmseXXXX_bpXXX.hdf5'.
• Training process will be saved in
  • 'LF_output/XXX_ckp/train_iterXXXXX.jpg'
  • 'LF_output/XXX_ckp/val_iterXXXXX.jpg'.

5. Stage 2: Run python train_sub_js.py

• Satge 1 model as pretrained, finetune load_weight_is=True
• path_weight='LF_checkpoint/SubFocal_sub_0.5_ckp/iter0049_valmse0.845_bp2.04.hdf5'

• Run python evaluation.py
  • path_weight='LF_checkpoint/SubFocal_sub_0.5_js_0.1_ckp/iter0010_valmse0.768_bp1.93.hdf5'

• Run python submission.py
  • path_weight='LF_checkpoint/SubFocal_sub_0.5_js_0.1_ckp/iter0010_valmse0.768_bp1.93.hdf5'
