AI总结:

提出VideoHandles,一种无需训练的视频3D物体组合编辑方法,通过将生成模型特征提升至共享3D重建并编辑后投影回各帧,实现时间一致的3D位置编辑,优于图像编辑基线。

摘要:

图像和视频编辑的生成方法使用生成模型作为先验,即使在信息不完整的情况下也能进行编辑,例如改变单张图像中显示的3D物体的组合。最近的方法在图像设置中展示了有前景的组合编辑结果,但在视频设置中,编辑方法一直专注于编辑物体的外观和运动,或相机运动,因此,编辑视频中物体组合的方法仍然缺失。我们提出VideoHandles作为一种在具有相机运动的静态场景视频中编辑3D物体组合的方法。我们的方法允许以时间一致的方式编辑视频所有帧中3D物体的3D位置。这是通过将生成模型的中间特征提升到所有帧共享的3D重建中,编辑该重建,并将编辑后的重建上的特征投影回每一帧来实现的。据我们所知,这是第一种在视频中编辑物体组合的生成方法。我们的方法简单且无需训练,同时优于最先进的图像编辑基线。

英文摘要:

Generative methods for image and video editing use generative models as priors to perform edits despite incomplete information, such as changing the composition of 3D objects shown in a single image. Recent methods have shown promising composition editing results in the image setting, but in the video setting, editing methods have focused on editing object's appearance and motion, or camera motion, and as a result, methods to edit object composition in videos are still missing. We propose \name as a method for editing 3D object compositions in videos of static scenes with camera motion. Our approach allows editing the 3D position of a 3D object across all frames of a video in a temporally consistent manner. This is achieved by lifting intermediate features of a generative model to a 3D reconstruction that is shared between all frames, editing the reconstruction, and projecting the features on the edited reconstruction back to each frame. To the best of our knowledge, this is the first generative approach to edit object compositions in videos. Our approach is simple and training-free, while outperforming state-of-the-art image editing baselines.
