📝 摘要(中文)

事件相机在高动态范围下提供了亮度变化线索,能够在传统RGB帧噪声或饱和的照明条件下进行有效恢复。为此,SEE Challenge 2026在ECCV 2026上组织,旨在评估事件引导的图像恢复能力。挑战使用SEE-600K数据集,包含来自真实场景的610,126个图像-事件观察,涵盖低光、正常光和高光条件。参与者可使用不同的时间上下文、架构和后处理策略,最终通过PSNR进行排名,SSIM作为辅助指标。约70个团队注册,15个有效提交,6个团队完成了技术验证,报告分析了曝光子集、测试案例和系统设计选择等。

🔬 方法详解

问题定义:本论文旨在解决在广泛照明范围内,特别是高动态范围下,图像恢复的挑战。现有方法在低光和高光条件下容易受到噪声和饱和的影响,导致恢复效果不理想。

核心思路:论文提出利用事件相机捕捉的亮度变化信息,结合RGB帧进行图像恢复。通过引导亮度调整,能够在不同照明条件下保持图像质量,提升恢复效果。

技术框架:整体架构包括数据采集、事件处理、亮度调整和图像恢复几个主要模块。首先,收集RGB帧和事件数据,然后进行同步处理,最后通过调整亮度统计信息来恢复图像。

关键创新:最重要的创新在于引入事件相机的亮度变化线索,使得在极端照明条件下的图像恢复成为可能。这一方法与传统的基于RGB的恢复方法有本质区别,后者往往无法有效处理高动态范围场景。

关键设计:在技术细节上,论文使用了特定的损失函数来优化图像恢复效果,并在网络结构中引入了多层次的特征提取模块,以增强对不同照明条件的适应性。

📄 摘要(原文)

Event cameras provide a high dynamic range and preserve brightness-change cues in lighting conditions where conventional RGB frames may be noisy or saturated. To benchmark event-guided restoration across a broad illumination range, we organized the SEE Challenge 2026 with the Event-Based Multimodal Vision Workshop at ECCV 2026. The task conditions restoration on one or more RGB frames, synchronized events, and a scalar target-brightness statistic provided by the organizers. It uses SEE-600K, which contains 610,126 image-event observations from 202 real-world scenes spanning low-light, normal-light, and high-light conditions with illumination variations of up to 1,000$\times$. The challenge follows an open-system protocol: participants may use different temporal contexts, architectures, pretrained weights, test-time augmentation, and post-processing strategies. PSNR determines the ranking, and SSIM is reported as a secondary metric. Around 70 teams registered interest and 15 valid CodaBench submissions were received. Six distinct teams completed organizer-side identity and technical verification, provided method descriptions, checkpoints, inference code, and instructions, and are included in the verified open-system ranking reported here. Beyond the ranking, this report analyzes exposure subsets, semantically distinct test cases, a shared failure pattern, system design choices, and inference strategies. The top systems obtain closely spaced average scores, while the best-performing method varies across cases and metrics; under severe underexposure, all verified systems retain visible local errors.
