Deformable 3D Convolution for Video Super-Resolution

Pytorch implementation of deformable 3D convolution network (D3Dnet). [PDF]

Our code is based on cuda and can perform deformation in any dimension of 3D convolution.

Overview

Architecture of D3Dnet


Architecture of D3D


Requirements

  • Python 3
  • pytorch (1.0.0), torchvision (0.2.2) / pytorch (1.2.0), torchvision (0.4.0)
  • numpy, PIL
  • Visual Studio 2015

Build

Compile deformable 3D convolution:

  1. Cd to code/dcn.
  2. For Windows users, run cmd make.bat. For Linux users, run bash make.sh. The scripts will build D3D automatically and create some folders.
  3. See test.py for example usage.

Datasets

Training dataset

  1. Download the Vimeo dataset and put the images in code/data/Vimeo.
  2. Cd to code/data/Vimeo and run generate_LR_Vimeo90K.m to generate training data as below:
  Vimeo
    └── sequences
           ├── 00001
           ├── 00002
           ├── ...
    └── LR_x4
           ├── 00001
           ├── 00002
           ├── ...		
    ├── readme.txt 
    ├── sep_trainlist.txt
    ├── sep_testlist.txt
    └── generate_LR_Vimeo90K.m      

Test dataset

  1. Download the dataset Vid4 and SPMC-11 dataset in https://pan.baidu.com/s/1PKZeTo8HVklHU5Pe26qUtw (Code: 4l5r) and put the folder in code/data.
  2. (optional) You can also download Vid4 and SPMC-11 or other video datasets and prepare test data in code/data as below:
 data
  └── dataset_1
         └── scene_1
               └── hr    
                  ├── hr_01.png  
                  ├── hr_02.png  
                  ├── ...
                  └── hr_M.png    
               └── lr_x4
                  ├── lr_01.png  
                  ├── lr_02.png  
                  ├── ...
                  └── lr_M.png   
         ├── ...		  
         └── scene_M
  ├── ...    
  └── dataset_N
