DuctTake 是一个旨在将场景的多个镜头实际合成到单个视频中的系统。当前的行业解决方案基于对象分割,这是一个需要大量手动输入和清理的难题,使得合成成为电影制作过程中昂贵的一部分。相反,我们的方法通过使用运动补偿 3D 图形切割视频体积来找到最佳时空接缝,从而将镜头合成在一起。我们详细描述了所需的组件、决策和新技术,这些组件、决策和新技术共同构成了一个用于合成高清视频的可用的交互式工具,并特别关注每个部分的运行时间和性能。我们通过提供各种示例并将结果质量和创建时间与专业艺术家使用当前最先进的工具制作的复合材料进行比较来验证我们的方法。
DuctTake is a system designed to enable practical compositing of multiple takes of a scene into a single video. Current industry solutions are based around object segmentation, a hard problem that requires extensive manual input and cleanup, making compositing an expensive part of the film‐making process. Our method instead composites shots together by finding optimal spatiotemporal seams using motion‐compensated 3D graph cuts through the video volume. We describe in detail the required components, decisions, and new techniques that together make a usable, interactive tool for compositing HD video, paying special attention to running time and performance of each section. We validate our approach by presenting a wide variety of examples and by comparing result quality and creation time to composites made by professional artists using current state‐of‐the‐art tools.
