Abstract

Inpainting is the problem of filling-in holes in images.Considerable progress has been made by techniques that use theimmediate boundary of the hole and some prior information on imagesto solve this problem. These algorithms successfully solve thelocal inpainting problem but they must, by definition, give thesame completion to any two holes that have the same boundary, evenwhen the rest of the image is vastly different. In this paper weaddress a different, more global inpainting problem. How can we usethe rest of the image in order to learn how to inpaint? We approachthis problem from the context of statistical learning. Given atraining image we build an exponential family distribution overimages that is based on the histograms of local features. We thenuse this image specific distribution to in paint the hole byfinding the most probable image given the boundary and thedistribution. The optimization is done using loopy beliefpropagation. We show that our method can successfully completeholes while taking into account the specific image statistics. Inparticular it can give vastly different completions even when thelocal neighborhoods are identical.
