EvTexture++: Event-Driven Texture Enhancement for Video Super-Resolution

Abstract

Event-based vision has drawn increasing attention owing to its distinctive properties, including ultra-high temporal resolution and extreme dynamic range. Recent works have introduced it to video super-resolution (VSR) to enhance flow estimation and temporal alignment. In contrast, this paper shifts the focus of event signals from motion refinement to texture enhancement in VSR. We propose EvTexture++, the first event-driven framework dedicated to texture enhancement in VSR. It leverages high-frequency spatiotemporal details from events to improve texture recovery. EvTexture++ incorporates a customized texture enhancement branch, along with an iterative texture enhancement module that progressively exploits high-temporal-resolution event information for texture restoration. This enables gradual refinement of texture regions across iterations, yielding more accurate and detailed high-resolution outputs …

本文提出EvTexture++,一种事件驱动的视频超分辨率纹理增强框架。与以往将事件用于运动估计不同,该方法利用事件的高频时空细节显式恢复纹理,通过定制纹理增强分支和迭代纹理增强模块,逐步挖掘高时间分辨率事件信息,实现纹理区域的渐进细化,从而生成更精确、细节更丰富的高分辨率视频。该框架还可作为即插即用模块提升现有VSR模型性能。
