1. What are the contributions mentioned in the paper "Interactive video completion" ?
The authors propose an interactive video completion method aiming for practical use in a digital production workplace.. According to their subjective evaluation, the videos completed with their method look significantly better than those with other state-of-the-art approaches.. However, video completion remains challenging for the following two reasons: 1 ) computational complexity increases with the number of video frames, which makes it difficult for the user to work interactively by trial and error ; 2 ) the quality of the completed video is often not satisfactory due to failures in estimating the dynamic motion of the camera and objects.. To address these issues, the authors propose a novel algorithm based on a flow-guided color estimation approach, which they demonstrate is useful for practical usage ( see Figure 1 ).. The authors present the following three technical contributions.. The authors propose to use the L data term for flow-field estimation but the L data term for color estimation.. The authors demonstrate that the manual modification on single or a few frames yields dramatic improvements in the quality of the completed video.. The authors demonstrate the successful completion of a variety of videos using their prototyping system.. To address these issues, the authors propose a fast flow-guided color estimation method that produces significantly better results.. The authors describe the naturalness of a completed video using the following energy function:. Furthermore, such artifacts are difficult to modify manually.
