Mask
The algorithm returns several vectorised masks of Post-inflammatory Hyperpigmentation for an image aligned with the face.
For a batch mode, all masks for left and right side pictures are attached to the frontal image result.
For a single image analysis - only frontal mask is available. For a batch - left, front and right masks are available.

This algorithm was developed under the supervision of a skin physiology specialist and can distinguish between 4 different acne manifestations, such as (1) papules, (2) pustules, (3) acne inflammation and (4) post-acne hyperpigmentation. This new algorithm will help to assess the severity of acne in a more detailed way and evaluate the dynamics of change of this skin condition.",
