SOF-VSR (Super-resolving Optical Flow for Video Super-Resolution)

Pytorch implementation of our ACCV 2018 paper "Learning for Video Super-Resolution through HR Optical Flow Estimation" and TIP 2020 paper "Deep Video Super-Resolution using HR Optical Flow Estimation".

Overview

Figure 1. Overview of our SOF-VSR network.

Figure 2. Comparison with the state-of-the-arts.

Requirements

• Python 3
• pytorch (0.4), torchvision (0.2)
• numpy, PIL
• Matlab (For PSNR/SSIM evaluation)

Datasets

We collect 145 1080P video clips from the CDVL Database for training.

We use the Vid4 dataset and a subset of the DAVIS dataset (namely, DAVIS-10) for benchmark test.

• Vid4(BaiduPan, GoogleDrive)
• DAVIS-10
  We use 10 scenes in the DAVIS-2017 test set including boxing, demolition, dive-in, dog-control, dolphins, kart-turn, ocean-birds, pole-vault, speed-skating and wings-trun.
