Abstract

We propose an exemplar-based video completion algorithm together with a geometry-guided space-time artifact reduction technique. The proposed completion algorithm is the video extension of an inpainting algorithm proven to be effective on still images. Then, the proposed space-time artifact reduction technique blends multiple patches, guided by a tensor model in order to preserve local structures and textures as much as possible. The two contributions we propose are complementary, and provide video completion results of good quality without block-effect artifacts.
基于范例的视频补全与几何制导的时空补丁混合
我们提出了一种基于示例的视频补全算法和一种几何引导的时空伪影减少技术。所提出的补全算法是一种被证明对静止图像有效的补全算法的视频扩展。然后,在张量模型的指导下,将多个斑块混合在一起,尽可能地保留局部结构和纹理。我们提出的两个贡献是互补的,并提供高质量的视频补全结果,没有块效应伪影。
