Classic Video Denoising in a Machine Learning World: Robust, Fast, and Controllable
- 用可微分的流程把传统去噪方法改造成可学习的参数预测器。
- 在真实视频上比深度学习方法更稳定，速度提升2~3倍。
- 支持用户调节去噪强度，适合需要精细控制的视频编辑场景。
去噪是交互式视频编辑等处理流程中的关键步骤，对质量、速度和用户控制要求高。尽管近期深度学习方法显著提升了去噪效果，但其在真实视频中因训练数据分布与实际噪声模式差异，易出现意外失败，且运行缓慢、缺乏可控性。相比之下，传统去噪方法在真实视频中表现可靠、速度快，但需为每段视频手动调参，费时且依赖经验。本文提出一种基于传统方法的可微分去噪流程，通过神经网络学习每段输入视频的最佳参数，实现鲁棒、高效且支持用户控制的去噪方案。
原文摘要 · Abstract (English)
Denoising is a crucial step in many video processing pipelines such as in interactive editing, where high quality, speed, and user control are essential. While recent approaches achieve significant improvements in denoising quality by leveraging deep learning, they are prone to unexpected failures due to discrepancies between training data distributions and the wide variety of noise patterns found in real-world videos. These methods also tend to be slow and lack user control. In contrast, traditional denoising methods perform reliably on in-the-wild videos and run relatively quickly on modern hardware. However, they require manually tuning parameters for each input video, which is not only tedious but also requires skill. We bridge the gap between these two paradigms by proposing a differentiable denoising pipeline based on traditional methods. A neural network is then trained to predict the optimal denoising parameters for each specific input, resulting in a robust and efficient approach that also supports user control.
