Calculated relative skin chromophore distribution of melanocytic nevus and vitiligo showing reduction of melanin-hemoglobin misestimation.
(a) Color cross-polarized image of nevus; (b) relative melanin (Mel); oxy-hemoglobin (oHb), deoxy-hemoglobin (Hb), total hemoglobin (tHb) and Oxygen Saturation Percentage (OSP) distribution for skin with nevus (c) before melanin correction, (d) after melanin correction; (e) Color cross-polarized image of vitiligo; (f) relative melanin (Mel), oxy-hemoglobin (oHb), deoxy-hemoglobin (Hb), total hemoglobin (tHb) and Oxygen Saturation Percentage (OSP) map of skin with vitiligo (g) before melanin correction, (h) after melanin correction (i) relative melanin, total hemoglobin concentration profile at A-A′ in melanocytic nevus (j) relative melanin, total hemoglobin concentration profile at B-B′ in vitiligo.
