论文摘要
视频流连续交付，以节省存储和设备内存的成本。用户设备上通常采用实时denoising算法，以消除视频流的拍摄和传输过程中所涉及的噪声。但是，基于滑动窗口的方法为单个输出和缺乏计算效率的多个输入帧提供了多个输入帧。最近的多输出推荐工作可以通过平行或经常性的框架传播双向时间功能，这要么在夹子的时间边缘上的性能下降，要么无法在线推断。在本文中，我们提出了一个双向流视频Denoisising（BSVD）框架，以实现具有过去和将来的暂时接收领域的流式传输视频的高保真实时denoing。在线推理的双向时间融合被认为不适用于Movinet。但是，我们引入了一个新型的双向缓冲块作为我们BSVD的核心模块，这使我们在管道风格的推理过程中成为可能。此外，我们的方法简洁且灵活，可用于非盲和盲视频降解。我们将模型与各种最先进的视频Denoising模型在定性和定量上进行了合成和真实噪声进行比较。我们的方法在恢复保真度和运行时的表现优于以前的方法。我们的源代码可在https://github.com/chenyangqiqi/bsvd上公开获得
Video streams are delivered continuously to save the cost of storage and device memory. Real-time denoising algorithms are typically adopted on the user device to remove the noise involved during the shooting and transmission of video streams. However, sliding-window-based methods feed multiple input frames for a single output and lack computation efficiency. Recent multi-output inference works propagate the bidirectional temporal feature with a parallel or recurrent framework, which either suffers from performance drops on the temporal edges of clips or can not achieve online inference. In this paper, we propose a Bidirectional Streaming Video Denoising (BSVD) framework, to achieve high-fidelity real-time denoising for streaming videos with both past and future temporal receptive fields. The bidirectional temporal fusion for online inference is considered not applicable in the MoViNet. However, we introduce a novel Bidirectional Buffer Block as the core module of our BSVD, which makes it possible during our pipeline-style inference. In addition, our method is concise and flexible to be utilized in both non-blind and blind video denoising. We compare our model with various state-of-the-art video denoising models qualitatively and quantitatively on synthetic and real noise. Our method outperforms previous methods in terms of restoration fidelity and runtime. Our source code is publicly available at https://github.com/ChenyangQiQi/BSVD
