Poisson Image EditingPatrick P erez Michel Gangnet Andrew Blake Microsoft Research UKAbstractUsing generic interpolation machinery based on solving Poissonequations, a variety of novel tools are introduced for seamless edit-ing of Image regions. The rst set of tools permits the seamlessimportation of both opaque and transparent source Image regionsinto a destination region. The second set is based on similar math-ematical ideas and allows the user to modify the appearance of theimage seamlessly, within a selected region. These changes can bearranged to affect the texture, the illumination, and the color of ob-jects lying in the region, or to make tileable a rectangular [Computer Graphics]: Picture/ImageGeneration Display algorithms; [Computer Graphics]:Methodology and Techniques Interaction techniques; [Im-age Processing and Computer Vision]: Enhancement Filtering;Keywor
Poisson partial differential equation with Dirichlet boundary con-ditions which species the Laplacian of an unknown function over the domain of interest, along with the unknown function values over the boundary of the domain. The motivation is twofold. First, it is well known to psychologists [Land and McCann 1971]
