我们介绍了Flexible Live‐Wire，这是Live‐Wire交互式分割技术的一种推广，使用浮动锚点。在我们的方法中，Live‐Wire的用户输入不再局限于像素级锚节点的设置，而是可以使用更通用的锚集。这些集合可以是任何维度、大小或连通性。该方法的通用性允许设计许多用户交互，同时提供与传统Live‐Wire相同的功能。特别是，我们通过基于特定基元设计四种新型Live-Wire交互来实验这种新的灵活性：绘制、捏、可能和拾取锚点。这些相互作用只是我们的概括所能实现的可能性的一个子集。此外，我们讨论了这种方法的计算方面，并提供了实际的解决方案，以减轻任何额外的开销。最后，我们说明了我们的方法和新的互动，通过几个例子分割。
We introduce Flexible Live‐Wire, a generalization of the Live‐Wire interactive segmentation technique with floating anchors. In our approach, the user input for Live‐Wire is no longer limited to the setting of pixel‐level anchor nodes, but can use more general anchor sets. These sets can be of any dimension, size, or connectedness. The generality of the approach allows the design of a number of user interactions while providing the same functionality as the traditional Live‐Wire. In particular, we experiment with this new flexibility by designing four novel Live‐Wire interactions based on specific primitives: paint, pinch, probable, and pick anchors. These interactions are only a subset of the possibilities enabled by our generalization. Moreover, we discuss the computational aspects of this approach and provide practical solutions to alleviate any additional overhead. Finally, we illustrate our approach and new interactions through several example segmentations.
