cd DecompositionForFusion

1. Download COCO: https://cocodataset.org/
2. Put your training images into any floder and modify the `option/train/SelfTrained_SDataset.yaml' to retarget the path.
3. Train DeFusion

   python selftrain.py --opt options/train/SelfTrained_SDataset.yaml

1. Download test dataset:
   1. Multi-exposure image fusion: MEFB:https://github.com/xingchenzhang/MEFB, SICE:https://github.com/csjcai/SICE.
   2. Multi-focus image fusion: Real-MFF:https://githubmemory.com/repo/Zancelot/Real-MFF, Dataset:https://github.com/xingchenzhang/MFIFB.
   3. Visible-infrared image fusion: RoadScene:https://github.com/jiayi-ma/RoadScene, TNO:https://figshare.com/articles/dataset/TNO_Image_Fusion_Dataset/1008029.
2. Modify test.py to select the data preprocess files for different tasks:
3. (Option) Our pretrained model is avaliable at Google Drive
4. Test DeFusion
   1. Test multi-exposure image fusion task on MEFB or SICE

   python test.py --opt options/test/MEF_Test_Dataset.yaml or
   python test.py --opt options/test/SMEF_Test_Dataset.yaml

   2. Test multi-focus image fusion task on Real-MFF or Dataset

   python test.py --opt options/test/MFF_Test_Dataset.yaml or
   python test.py --opt options/test/EMFF_Test_Dataset.yaml

   3. Test visible infrared image fusion task on RoadScene or TNO

   python test.py --opt options/test/IVF_Test_Dataset.yaml or
   python test.py --opt options/test/TIVF_Test_Dataset.yaml
