我们提出软剪刀，一个交互式的工具，用于提取阿尔法蒙版的前景对象在实时。我们最近提出了一种新的离线抠图算法，能够为复杂的前景对象（如毛茸茸的动物）提取高质量的抠图[Wang and Cohen 2007]。在本文中，我们都提高了我们的离线算法的质量，并给它的能力，在一个在线的交互式设置，以增量更新的遮片。我们的实时系统有效地估计前景颜色，从而允许双方的哑光和最终的复合材料，以立即显示为用户大致沿沿着前景对象的边缘绘画。此外，我们的系统可以动态地调整剪切画笔的宽度和边界条件，以近似地捕捉前景对象的边界，该边界位于前景对象的路径上。这些在速度和准确性方面的优势创建了第一个高质量图像抠图和合成的交互式工具。
We present Soft Scissors, an interactive tool for extracting alpha mattes of foreground objects in realtime. We recently proposed a novel offline matting algorithm capable of extracting high-quality mattes for complex foreground objects such as furry animals [Wang and Cohen 2007]. In this paper we both improve the quality of our offline algorithm and give it the ability to incrementally update the matte in an online interactive setting. Our realtime system efficiently estimates foreground color thereby allowing both the matte and the final composite to be revealed instantly as the user roughly paints along the edge of the foreground object. In addition, our system can dynamically adjust the width and boundary conditions of the scissoring paint brush to approximately capture the boundary of the foreground object that lies ahead on the scissor's path. These advantages in both speed and accuracy create the first interactive tool for high quality image matting and compositing.
