We further show that traditional sparse-coding-based SR methods can also be viewed as a deep convolutional network.
#2 best model for Video Super-Resolution on Xiph HD - 4x upscaling
This means that the super-resolution (SR) operation is performed in HR space.
We also propose a first set of metrics to quantitatively evaluate the accuracy as well as the perceptual quality of the temporal evolution.
The feed-forward architectures of recently proposed deep super-resolution networks learn representations of low-resolution inputs, and the non-linear mapping from those to high-resolution output.
#6 best model for Image Super-Resolution on Set5 - 4x upscaling
In this work, we propose a novel Video Restoration framework with Enhanced Deformable networks, termed EDVR, to address these challenges.
Many video enhancement algorithms rely on optical flow to register frames in a video sequence.
#4 best model for Video Frame Interpolation on Vimeo90k
In this paper, we show that proper frame alignment and motion compensation is crucial for achieving high quality results.
#6 best model for Video Super-Resolution on Vid4 - 4x upscaling
We propose a novel end-to-end deep neural network that generates dynamic upsampling filters and a residual image, which are computed depending on the local spatio-temporal neighborhood of each pixel to avoid explicit motion compensation.
#2 best model for Video Super-Resolution on Vid4 - 4x upscaling
Recent advances in video super-resolution have shown that convolutional neural networks combined with motion compensation are able to merge information from multiple low-resolution (LR) frames to generate high-quality images.
