Effective Color Ink Diffusion Synthesis

Our previous work proposed a non-stroke, image-based rendering algorithm for automatically synthesizing a reference image with color ink diffusion style. However, our previous work also showed drawbacks of "color shifting" and "detail missing. " In this paper, we present a new and effective color ink diffusion synthesis (ECIDS) algorithm. In particular, we propose a new Kubelka-Munk equation (SK-M) to properly mix pigment color. This new equation produces a resultant image that has a tone visually similar to the reference image. In addition, we present a new overlapping equation (NOL) to properly overlap deposit layer with diffusion layer. Thus, the resultant image can show more ink diffusion details than our previous work. Experimental results demonstrate that this new algorithm can effectively produce visually pleasing results better than our previous work.
