Video super-resolution based on automatic key-frame selection and feature-guided variational optical flow

作者：

Highlights：

• An automatic key-frame selection method is proposed.

• Video super-resolution based on feature-guided variational optical flow is proposed.

• This can deal with the case of small structures with large displacement.

• Our method has the best visual quality and the highest PSNR.
