In the reproduction of human images in posters, TV commercials, movies
and other media, the skin melanin texture of the photograph is often controlled
manually by an experienced operator in a time
consuming process. As such, a tool able to assist in controlling the texture
would be useful in the fields of computer graphics and imaging to accelerate
the reproduction processes. 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.
