Pigmentation Algorithm

About Algorithm

1. This Algorithm estimates the visible presence and severity of local patches of skin of size up to several cm, that are darker in colour than the normal surrounding skin due to the local excess of melanin.

2. This Algorithm estimates indicated skin health parameters on: forehead, right cheek, left cheek, nose and chin area.

3. The Main Metric for this Algorithm is the Pigmentation Score, with a range from 0 to 100.

   1. Values from 80 to 100 are considered as a relatively good skin condition.

   2. Values from 50 to 80 are considered as visible pigmentation spots presence.

   3. Values below 50 are considered as an alerting skin condition, that might require specialist attention.

   4. Pigmentation Score is a non-linear combination of the Submetrics.

4. There are several Submetrics for this Algorithm:

   • Number of pigmentation spots.

   • Average intensity of pigmentation.

   • Average size of pigmentation spots.

   • Standard deviation of pigmentation spots size.

   • Pigmentation density score — the ratio of skin area covered by detected pigmented spots.
