摘要:

文本到图像(T2I)扩散模型近期在视频编辑领域展现了显著进展。然而,现有的视频编辑方法受到高计算开销和内存消耗的严重限制。此外,这些方法常常牺牲视觉保真度,导致不理想的时间不一致性以及模糊和明显马赛克状图案等伪影。我们提出了Edit-Your-Interest,一种轻量级、文本驱动、零样本的视频编辑方法。Edit-Your-Interest引入了一个时空特征记忆库,用于缓存先前帧的特征,与全序列时空建模方法相比,显著降低了计算开销。具体来说,我们首先引入了一个时空特征记忆库(SFM),旨在高效缓存并保留由空间注意力处理的关键图像令牌。其次,我们提出了特征最相似传播(FMP)方法。FMP将先前帧中最相关的令牌传播到后续帧,从而保持时间一致性。最后,我们引入了一种SFM更新算法,持续刷新缓存的特征,确保其在视频序列中的长期相关性和有效性。此外,我们利用交叉注意力图自动提取感兴趣实例的掩码。这些掩码无缝集成到扩散去噪过程中,能够对目标对象进行细粒度控制,使Edit-Your-Interest能够执行高度精确的编辑,同时稳健地保持背景完整性。大量实验明确表明,所提出的Edit-Your-Interest在效率和视觉保真度方面均优于最先进的方法,验证了其卓越的有效性和实用性。

英文摘要:

Text-to-image (T2I) diffusion models have recently demonstrated significant progress in video editing. However, existing video editing methods are severely limited by their high computational overhead and memory consumption. Furthermore, these approaches often sacrifice visual fidelity, leading to undesirable temporal inconsistencies and artifacts such as blurring and pronounced mosaic-like patterns. We propose Edit-Your-Interest, a lightweight, text-driven, zero-shot video editing method. Edit-Your-Interest introduces a spatio-temporal feature memory to cache features from previous frames, significantly reducing computational overhead compared to full-sequence spatio-temporal modeling approaches. Specifically, we first introduce a Spatio-Temporal Feature Memory bank (SFM), which is designed to efficiently cache and retain the crucial image tokens processed by spatial attention. Second, we propose the Feature Most-Similar Propagation (FMP) method. FMP propagates the most relevant tokens from previous frames to subsequent ones, preserving temporal consistency. Finally, we introduce an SFM update algorithm that continuously refreshes the cached features, ensuring their long-term relevance and effectiveness throughout the video sequence. Furthermore, we leverage cross-attention maps to automatically extract masks for the instances of interest. These masks are seamlessly integrated into the diffusion denoising process, enabling fine-grained control over target objects and allowing Edit-Your-Interest to perform highly accurate edits while robustly preserving the background integrity. Extensive experiments decisively demonstrate that the proposed Edit-Your-Interest outperforms state-of-the-art methods in both efficiency and visual fidelity, validating its superior effectiveness and practicality.
