摘要:

视频超分辨率是一种将低分辨率视频转换为高分辨率视频的技术,近年来受到越来越多的关注。在这项工作中,我们提出了一种新的方法,可以有效地将时间信息在一个层次的方式。输入序列被分成若干组,每组对应于一种帧速率。这些组提供补充信息以恢复参考帧中丢失的细节,其进一步与注意模块和深度组内融合模块集成。此外,提出了一种快速的空间对齐来处理具有大运动的视频。大量的结果表明,该模型在处理各种运动的视频的能力。它在几个基准数据集上实现了对最先进方法的良好性能。

英文摘要:

Video super-resolution, which aims at producing a high-resolution video from its corresponding low-resolution version, has recently drawn increasing attention. In this work, we propose a novel method that can effectively incorporate temporal information in a hierarchical way. The input sequence is divided into several groups, with each one corresponding to a kind of frame rate. These groups provide complementary information to recover missing details in the reference frame, which is further integrated with an attention module and a deep intra-group fusion module. In addition, a fast spatial alignment is proposed to handle videos with large motion. Extensive results demonstrate the capability of the proposed model in handling videos with various motion. It achieves favorable performance against state-of-the-art methods on several benchmark datasets.
