Getting Started

Prerequisites

Tested environment

1. Setup environment

   • Option 1. install from scratch

     $ git clone https://github.com/codeslake/DMENet.git
     $ cd DMENet
     
     # for CUDA10
     $ conda create -y --name DMENet python=3.6 && conda activate DMENet
     $ sh install_CUDA10.0.sh
     
     # for CUDA11 (the name of conda environment matters)
     $ conda create -y --name DMENet_CUDA11 python=3.6 && conda activate DMENet_CUDA11
     $ sh install_CUDA11.1.sh

   • Option 2. docker

     $ nvidia-docker run --privileged --gpus=all -it --name DMENet --rm codeslake/dmenet:CVPR2019 /bin/zsh
     $ git clone https://github.com/codeslake/DMENet.git
     $ cd DMENet
     
     # for CUDA10
     $ conda activate DMENet
     
     # for CUDA11
     $ conda activate DMENet_CUDA11

2. Download and unzip datasets (OneDrive | Dropbox) under [DATASET_ROOT].

   [DATASET_ROOT]
    ├── train
    │   ├── SYNDOF
    │   ├── CUHK
    │   └── Flickr
    └── test
        ├── CUHK
        ├── RTF
        └── SYNDOF
   

   Note:

   • [DATASET_ROOT] is currently set to ./datasets/. It can be specified by modifying config.data_offset in ./config.py.

3. Download pretrained weights of DMENet (OneDrive | Dropbox) and unzip it as in [LOG_ROOT]/DMENet_CVPR2019/DMENet_BDCS/checkpoint/DMENet_BDCS.npz ([LOG_ROOT] is currently set to ./logs/).

4. Download pretrained VGG19 weights (OneDrive | Dropbox) and unzip as in pretrained/vgg19.npy (for training only).

Logs

• Training and testing logs will be saved under [LOG_ROOT]/DMENet_CVPR2019/[mode]/:

  [LOG_ROOT]
   └──DMENet_CVPR2019
      ├── [mode]
      │   ├── checkpoint      # model checkpoint
      │   ├── log             # scalar/image log for tensorboard
      │   ├── sample          # sample images of training
      │   └── result          # resulting images of evaluation
      └── ...
  

  [LOG_ROOT] can be modified with config.root_offset in ./config.py.

Testing final model of CVPR 2019

Please note that due to the server issue, the checkpoint used for the paper is lost.
The provided checkpoint is the new checkpoint that shows the closest evaluation results as in the paper.

Check out updated performance with the new checkpoint.

• Test the final model by:

  python main.py --mode DMENet_BDCS --test_set CUHK

  Testing results will be saved in [LOG_ROOT]/DMENet_CVPR2019/[mode]/result/[test_set]/:

  ...
  [LOG_ROOT]/DMENet_CVPR2019/[mode]/result/
   └── [test_set]
       ├── image                     # input defocused images
       ├── defocus_map               # defocus images (network's direct output in range [0, 1])
       ├── defocus_map_min_max_norm  # min-max normalized defocus images in range [0, 1] for visualization
       └── sigma_map_7_norm          # sigma maps containing normalized standard deviations (in range [0, 1]) for a Gaussian kernel. For the actual standard deviation value, one should multiply 7 to this map.
  

  Quantitative results are computed from matlab. (e.g., evaluation on the RTF dataset).

  • Options
    • --mode: The name of a model to test. The logging folder named with the [mode] will be created as [LOG_ROOT]/DMENet_CVPR2019/[mode]/. Default: DMENet_BDCS
    • --test_set: The name of a dataset to evaluate. CUHK | RTF0 | RTF1 | RTF1_6 | random. Default: CUHK
      • The folder structure can be modified in the function get_eval_path(..) in ./config.py.
      • random is for testing models with any images, which should be placed as [DATASET_ROOT]/test/random/*.[jpg|png].

• Check out the evaluation code for the RTF dataset, and the deconvolution code.

Training & testing the network

• Train the network by:

  python main.py --is_train --mode [mode]

  Note:

  • If you train DMENet with newly generated SYNDOF dataset from this repo, comment this line and uncomment this line before the training.

• Test the network by:

  python main.py --mode [mode] --test_set [test_set]

  • arguments
    • --mode: The name of a model to train. The logging folder named with the [mode] will be created as [LOG_ROOT]/DMENet_CVPR2019/[mode]/. Default: DMENet_BDCS
    • --is_pretrain: Pretrain the network with the MSE loss (True | False). Default: False
    • --delete_log: Deletes [LOG_ROOT]/DMENet_CVPR2019/[mode]/* before training begins (True | False). Default: False
