N2 - In this study, skin erythema assessment of 90 rosacea patients was estimated by a simple, low-cost RGB imaging device. RGB imaging can be used to estimate the level of redness by analyzing absorption in the green and red spectral channels of a simple RGB camera, as there is an increased absorption of skin chromophore hemoglobin in the spectral range of 500-600nm (corresponding to the green channel) and very little absorption of hemoglobin in the spectral range of 600-700nm (red channel). Different algorithms are used for comparison, and a new erythema index assessment algorithm is proposed and clinically validated. Comparison with dermatologist's visual assessment shows high correlation.
