针对数字化制作环境中的实际应用，提出了一种交互式视频补全方法。早期自动解决方案的结果通常需要进行大量的手动修改才能在实践中使用。为了减少这种繁重的任务，我们的方法提供了一种高效的编辑工具。我们的迭代算法估计了视频中时空空洞中的流场和颜色。与以前的方法一样，我们的算法使用L-1数据项来估计流场。然而，我们使用了一种新的L-2数据项来估计时间相干颜色转变。我们的图形处理单元实现使用户能够通过绘制孔来交互地完成视频，并立即从视频中移除对象。此外，我们的方法成功地对设计者初始化的稀疏修改进行了内插。根据我们的主观评价，用我们的方法完成的视频看起来明显好于其他最先进的方法。
We propose an interactive video completion method aiming for practical use in a digital production workplace. The results of earlier automatic solutions often require a considerable amount of manual modifications to make them usable in practice. To reduce such a laborious task, our method offers an efficient editing tool. Our iterative algorithm estimates the flow fields and colors in space-time holes in the video. As in earlier approaches, our algorithm uses an L-1 data term to estimate flow fields. However, we employ a novel L-2 data term to estimate temporally coherent color transitions. Our graphics processing unit implementation enables the user to interactively complete a video by drawing holes and immediately removes objects from the video. In addition, our method successfully interpolates sparse modifications initialized by the designer. According to our subjective evaluation, the videos completed with our method look significantly better than those with other state-of-the-art approaches.
