Figure 1 : From three pixel-aligned video streams with varying focus we automatically extract a trimap. We then solve for the most probable matte by constrained optimization and post-process to remove noise from ill-conditioned pixels. Defocus matting pulls mattes with sub-pixel detail from natural images without user intervention and in situations where blue screen matting is impractical. Abstract Video matting is the process of pulling a high-quality alpha matte and foreground from a videodoi:10.1145/1186822.1073231 fatcat:mvvgl4p2jrd2vfj2obmc26la2y
