In this research, we evaluate the visibility of age spot and freckle with changing the blood volume based on the actual facial color images and compare the result with that of pigmentation patterns generated by simulated spectral reflectance. We acquire the concentration distribution of melanin, hemoglobin and shading components by applying the independent component analysis on a facial color image. We reconstruct images by using the obtained melanin and shading concentration and the changed hemoglobin concentration to generate facial images with changing the blood volume. Finally, we evaluate the visibility of pigmentations using these images and compare with the result of pigmentation patterns based on simulated reflectance. In our previous study, we have already evaluated the visibility of pigmentation patterns, and the visibility became lower as the blood volume increases. However, we can see that a specific blood volume reduce the visibility of the actual pigmentations from the result of evaluating the skin color images.

More about this publication?
  • CIC is the premier annual technical gathering for scientists, technologists, and engineers working in the areas of color science and systems, and their application to color imaging. Participants represent disciplines ranging from psychophysics, optical physics, image processing, color science to graphic arts, systems engineering, and hardware and software development. While a broad mix of professional interests is the hallmark of these conferences, the focus is color. CICs traditionally offer two days of short courses followed by three days of technical sessions that include three keynotes, an evening lecture, a vibrant interactive (poster) papers session, and workshops. An endearing symbol of the meeting is the Cactus Award, given each year to the author(s) of the best interactive paper; there are also Best Paper and Best Student Paper awards.
