matting, alpha channel, image compositing,
In this paper, we formulate the problem of natural image matting as
one of solving Poisson equations with the matte gradient field. Our
approach, which we call Poisson matting, has the following advantages.
First, the matte is directly reconstructed from a continuous
matte gradient field by solving Poisson equations using boundary
information from a user-supplied trimap. Second, by interactively
manipulating the matte gradient field using a number of filtering
tools, the user can further improve Poisson matting results locally
until he or she is satisfied. The modified local result is seamlessly
integrated into the final result. Experiments on many complex natural
images demonstrate that Poisson matting can generate good
matting results that are not possible using existing matting techniques.
