Abstract
This paper proposes an automatic video matting method that uses hybrid video object segmentation and closed-form matting. Hybrid video object segmentation, based on background construction-based video object segmentation and foreground extraction-based video object segmentation, is used to obtain reliable foreground objects. Next, the trimaps are automatically generated using two different scanning windows from the hybrid video object segmentation results. Finally, closed-form matting is used, with the automatically generated trimaps, to yield the alpha mattes and the foreground objects with an opacity estimate. Experimental results show that the proposed method outperforms state-of-the-art automatic video matting methods based on closed-form matting.
