For click-based interactive segmentation methods, reducing the number of clicks required to obtain a desired segmentation result is essential. Although recent click-based methods yield decent segmentation results, we observe that substantial amount of clicks are required to segment elongated regions. To reduce the amount of user-effort required, we propose using lines instead of clicks for such cases. In this paper, an interactive segmentation algorithm which adaptively adopts either clicks or lines as input is proposed. Experimental results demonstrate that using lines can generate better segmentation results than clicks for several cases.

翻译：对于基于点击的交互式分割方法，减少获取所需分割结果所需的点击次数至关重要。尽管近期基于点击的方法能产生不错的分割结果，但我们观察到分割细长区域时仍需要大量点击。为减少用户操作量，我们提出在此类场景中使用线条替代点击。本文提出了一种自适应采用点击或线条作为输入的交互式分割算法。实验结果表明，在多种情况下，使用线条能比点击生成更优的分割结果。
