Independent color-channel adjustment for seamless cloning based on Laplacian-membrane modulation

Image compositing combines visual elements from multiple images aiming to produce natural-looking results. Poisson-image-editing methods can generate seamless compositions, but introduce color changes in the inserted elements, which often generate unrealistic and unpleasing results. Recently, Henz et al. have presented an approach for controlling the amount of color changes in the inserted image patches (Henz et al., 2015 ). We improve their work by using new sets of color basis vectors tailored to maximize color separation on transition zones, and by independently controlling the amount of adjustment on individual color channels. With our technique, artists have greater control over the final composites׳ color, besides significantly enhancing their freedom to achieve effects that were unreachable by previous methods. We performed two user studies to evaluate the perceptual effectiveness of the proposed technique. The studies show that our method provides the flexibility to produce even more natural and pleasing composites than previous seamless-cloning techniques.
