Pigmentation

Haut.AI provides an AI algorithm that estimates pigmented spots for different facial areas and the whole face.

Description

Pigmentation refers to the coloring of the skin and is determined mainly by the brown pigment melanin. Pigmentation takes into account the prominence of dark spots, moles and freckles. Hyperpigmentation is usually harmless but can sometimes be caused by an underlying medical condition. In case of very low parameter values, it is recommended to consult a specialist.

The higher the value of this parameter, the fewer pigmented spots you have.

"algorithm_tech_name": "pigmentation"

area_name

The algorithm returns metrics and sub-metrics for the following facial areas:

  • face

  • nose_upper_triangle

  • right_cheek_wide

  • left_cheek_wide

  • forehead

  • chin_wide

main_metric

The main metric is an overall score indicating the pigmented spots for each area_name

            },
  • value the pigmentation score ranges from [0,100]The higher the value of this parameter, the fewer pigmented spots

  • "widget_type": "bad_good_line" indicates that a higher value is better

The algorithm returns sub-metrics for each area_name
