'''Gradient-___domain image processing''' is a relatively new type of [[digital image processing]] that operates on the differences between neighboring pixels, rather than on the pixel values directly. An [[image gradient]] represents the derivative of an image, so the goal of gradient-___domain processing involves solving an integralis to extractobtain an image fromby integrating the gradient, which requires solving [[Poisson's equation]].<ref name="Bhat2010">Bhat, Pravin, et al.
