Segmentation methods for acne vulgaris images: Proposal of a new methodology applied to fluorescence images

Acne vulgaris is one of the most common human pathologies worldwide. Its prevalence causes a high healthcare expenditure. Acne healthcare costs and effects on individuals' quality of life lead to the need of analysing current acne evaluation, treatment and monitoring methods. One of the most common ones is manual lesion counting by a dermatologist. However, this technique has several limitations, such as time spent. That is the reason why the development of new computer‐assisted techniques is needed in order to automatically count the acne lesions.
