Figure 1: Our system computes a high quality matte (a) and a novel composite (b) in realtime as the user roughly paints the foreground
boundary. Our system makes is easy to create new composites (c) very quickly.
We present Soft Scissors, an interactive tool for extracting alpha mat-
tes 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 Co-
hen 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 esti-
mates 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 dy-
