Accuracy of the skin model in quantifying the thickness of papillary dermis using colour images

The thickness of papillary dermis is an important parameter in optical model of the skin [1, 2]. Any change in the thickness produces di erent model with speci c skin colouration. This paper investigate the accuracy of the skin imaging system in quantifying the thickness of papillary dermis and also epidermal melanin. It also evaluates the e ectiveness of infrared primaries in contrast to conventional red, green and blue primaries for measuring the two parameters. Error analysis demonstrates that infrared primaries are more reliable for such a measurement.
