摘要： 基于二维均值坐标插值的视频融合方法会产生局部色彩失衡和画面闪烁等失真现象。为此，提出一种基于优化三维均值坐标的视频融合方法。在连续的视频序列上建立三维均值坐标，根据不同的边界情况优化均值坐标的计算，并利用图像matting技术提高融合效果。实验结果表明，与现有方法相比，该方法可以更有效地提高融合质量。

Abstract: Interpolation-based fusion method using 2D mean-value coordinates may product some unnatural effects. Aiming at this problem, this paper presents a new method of video fusion to avoid these flaws. Based on 3D mean-value coordinates, a boundary-aware algorithm is provided to optimize the determination of 3D mean-value coordinates. Matting-based methods are used to refine produced video. Experimental results show that this method can enhance the quality of composition more effectively compared with the existing approaches.

Key words: mean-value coordinates, hybrid fusion, video fusion, video processing, temporal and spatial consistency
