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;Keywords:Interactive Image Editing , Image gradient, guided in-terpolation, Poisson equation, seamless cloning, selection editing1 IntroductionImage Editing tasks concern either global changes (color/intensitycorrections, lters, deformations) or local changes con ned to a se-lection.
cian pyramid thus obtained. The technique results in multiresolu-tion mixing where nest details are averaged very locally around the boundary of the selection, while lower frequencies are mixed over much larger distances around these boundaries. This fast tech-nique achieves an approximate insertion of the source Laplacian
