ZOOM#29: Pigmentation analysis by Pixience

Sunlight exposure, hormones, skin damage, and exposure to certain chemicals affect melanin production and brown spots or discoloration may appear with age.

Using its patented lighting and a color calibration process, the C-Cube converts image pixels into CIE L*a*b* measurements. They are correlated with spectrocolorimeters (R²=0.97). The pigmentation index is correlated with melanin content of the skin and represents the distance to a reference dark skin which maximizes melanin content.

The calculation is done for each pixel and the result is displayed using a color map. Using ROI, the average, minimum and maximum values are processed and saved.
