摘要 基于鲁棒抠图算法提出了一种鲁棒视频抠图算法。新算法给出了一种基于少量手工标记的Strokes生成Trimap的方法,为视频帧半自动生成较为粗糙的Trimap划分,同时结合标记传递策略大大减少视频抠图过程中的手工标记操作。理论分析和实验结果证明鲁棒视频抠图算法能够获得较优的视频抠图结果。 Proposed a robust video matting algorithm that extends robust matting to video processing. This algorithm introduced a Strokes-based Trimap generating method and a user-mark propagation strategy to reduce the laborious manual work in video matting. Theoretical analysis and experimental results show that robust video matting can achieve effective video matting results.
