Skin Parameter Map Retrieval from a Dedicated Multispectral Imaging System Applied to Dermatology/Cosmetology

Table 1

Five skin parameters used in the retrieval algorithm. The range of each parameter is selected from the literature. The retrieval parameters are bounded to these limits.

Skin parameter	Symbol	Range
Melanin concentration	𝑓mel	1.3 to 45%
Epidermis thickness	𝐷epi	0.01–0.15 mm
Volume fraction of haemoglobin	𝑓blood	0.2–7%
Oxygenated haemoglobin	𝐶oxy	25–90%
Dermis thickness	𝐷dermis	0.6–3 mm
