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.
leverages classic cloning tools, both in terms of ease of use and ca-pabilities. The resulting cloning allows the user to remove and add objects seamlessly. By mixing suitably the gradient of the source image with that of the destination image, it also becomes possible to add transparent objects convincingly. Furthermore, objects with
