This paper describes a novel technique (deviation mapping) that generates images with artistic appearances, e.g., spray painted wall, embossment, cashmere painting, etc. Our technique employs a deviation map constructed from a single background image in the image generation process. Instead of recovering the exact geometry from the background image, the deviation map can be regarded as a virtual surface. This virtual surface is then painted with a foreground image and illuminated to generate the final result. Interestingly, the synthesized images exhibit some artistic appearances. Our method is very fast and very simple to implement.
