Video object removal is a challenging task in video processing that often
requires massive human efforts. Given the mask of the foreground object in each
frame, the goal is to complete (inpaint) the object region and generate a video
without the target object. While recently deep learning based methods have
achieved great success on the image inpainting task, they often lead to
inconsistent results between frames when applied to videos. In this work, we
propose a novel learning-based Video Object Removal Network (VORNet) to solve
the video object removal task in a spatio-temporally consistent manner, by
combining the optical flow warping and image-based inpainting model.
Experiments are done on our Synthesized Video Object Removal (SVOR) dataset
based on the YouTube-VOS video segmentation dataset, and both the objective and
subjective evaluation demonstrate that our VORNet generates more spatially and
temporally consistent videos compared with existing methods.

本文提出了一种基于深度学习的视频物体移除网络（VORNet），该方法通过结合光流修补和基于图像修补模型的方法，在时空上保持稳定性，对生成的视频进行了客观和主观评估，结果表明与现有方法相比，我们的 VORNet 在时空上生成了更加稳定的视频。
