Depth maps are becoming a readily available commodity of the stereo pipeline. We propose to make use of this new free information to improve a key step of postproduction that is matting. We extend the work of Levin et al on closed form matting to introduce two new depth-aware techniques. First we explore how depth can be used as an extra channel in the matting process. Then we see how depth can be used as a diffusion guide for matting. Our results show that both techniques can reduce the amount of time needed to pull a matte.
