A Perceptually Motivated Method to Control Reconstruction Errors in Gradient-based Image Compositing

We propose a simple algorithm to control the spatial location of reconstruction errors inherent in gradient-based image compositing. We build upon the classical Poisson equation and add a weighting term that controls where reconstruction errors can occur. We define this term in such a way that residuals are mainly located in textured regions where they are less visible. Our approach is independent of how the composited gradient field has been built and is complementary to the methods that focus on this aspect. Our approach retains the simplicity of the traditional Poisson equation while producing more pleasing composites.
