| Abstrakt v dalším jazyce: | This paper presents a new approach for video completion of high-resolution video sequences. Current state-ofthe- art exemplar-based methods that use non-parametric patch sampling work well and provide good results for low-resolution video sequences. Unfortunately, because of memory consumption problems and long computation times, these methods handle only relatively low-resolution video sequences. This paper presents a video completion method that can handle much higher resolutions than previous ones. First, to address the problem of long computation times, a dual inpainting-sampling filling-order completion method is proposed. The quality of our results is then significantly improved by a second innovation introducing a coherence-based matches refinement that conducts intelligent and localized searches without relying on approximate searches or compressed data. Finally, with respect to the computation times and memory problems that prevent high-resolution video completion, the third innovation is a new localized search completion approach, which also uses uncompressed data and an exact search. Combined together, these three innovations make it possible to complete high-resolution video sequences, thus leading to a significant increase in resolution as compared to previous works. |
