摘要: 传统视频分割算法无法处理视频中庞大的数据量,且分割结果需要保持时空连续性。针对该问题,提出一种基于三维体的多分辨率视频分割算法。在三维空间中对整个视频体进行分割,以保证时空连续性,采用多分辨率的思想,减少计算开销。实验结果表明,该算法能减少传统分割算法的时空耗费,修正连续帧的局部分割结果。

Abstract: This paper proposes a novel 3D body based multi-resolution video segmentation algorithm for solving some difficulties in video area, such as the tremendous data volume and temporally inconsistency. It segments the whole video volume to ensure the temporally coherent result. Meanwhile, it uses the multi-resolution method to reduce the computational cost. Experimental results show that, the approach greatly reduces the time and space cost of the traditional segmentation approach and revises the part segmentation result of continuation frame.
