Abstract
In the medical imaging field, skin responses against various stresses give us significant information for monitoring human conditions. In this research, we have developed a real-time video signal processing system which can estimate and display the mapping of pigmentation in human skin. The maps of melanin, oxy-hemoglobin and deoxy-hemoglobin densities in skin are converted from RGB image using three pre-computed color conversion look up tables. This system is applied to observe the changes in pigmentation during the occlusion and release of human middle finger and also during anaerobic exercise. It became possible to watch the human homeostasis by disturbance in real-time with the developed system.
