Real-time image-based control of skin melanin texture

In this paper, we present a novel process to control the skin melanin texture over a continuous range. The process is implemented on graphics hardware and can achieve real-time processing for a livevideo stream. A component map of melanin texture is utilized, which was extracted from a skin color image by our previous method [Tsumura et al. 2003]. A feature vector is calculated from the extracted melanin texture and shifted in a feature space to control the melanin texture over a continuous range. The feature space is constructed based on the texture database to extract physiologically plausible changes in the melanin texture.
