摘要: A prototype low-cost RGB imaging system consisting of a commercial CMOS sensor, light-emitting diode ring light illuminator, and set polarizers was designed tested for mapping the skin erythema index, in order to monitor recovery after phototherapy vascular lesions, such as hemangiomas telangiectasias. The contrast index (CEI) proposed parameter quantitative characterization lesions. Skin characterized decrease CEI value relative before treatment. This approach clinically validated by examining 31 lesions phototherapy.
