Abstract
An illumination manipulation scheme for a single object in still images is proposed in this paper. By using the dichromatic-based model, the reflection component can be resolved through a single-image specular reflection removal method with the characteristics of color constancy. Then, virtual illumination effect can be made through the recombination with the reflection component. The scenery illumination can be estimated using the proposed automatic method without knowing the illumination spectra, three-dimensional object modeling, or texture databases. Experimental results show that the method is useful for handling the images with a single multicolor object in scenes.
