'''Gradient ___domain image processing''', also called '''Poisson image editing''',<ref name="Perez2003"/> is a type of [[digital image processing]] that operates on the differences between neighboring pixels, rather than on the pixel values directly. Mathematically, an [[image gradient]] represents the [[derivative]] of an image, so the goal of gradient ___domain processing is to construct a new image by [[integral|integrating]] the gradient, which requires solving [[Poisson's equation]].<ref name="Bhat2010">Bhat, Pravin, et al.
