Evidence behind automated VASI scoring for vitiligo, covering the validation of the depigmentation segmentation model, the DIQA image quality gate, and the foundational VASI references.

End-to-end clinical trial workflow for VASI endpoints, covering protocol design, site setup, patient enrolment, in-clinic body and face capture, automated VASI scoring, change from baseline and alerts, data export, and EDC integration.

How images are captured for automated VASI scoring in vitiligo: the standard body and face capture set, DIQA quality control, patient preparation, and site standardisation.

Known limitations of automated VASI scoring for vitiligo, covering differential diagnosis of light skin, the degree of depigmentation, very fair skin, regions outside the capture set, ultraviolet imaging, endpoints not measured, and how each limitation is mitigated.

Technical detail on how pixel-level depigmentation segmentation produces the VASI score for vitiligo, covering the six body sites, the views and their share of the body surface, the VASI formula, the facial and total forms, responder definitions against baseline, and comparison with manual assessment.

Automated VASI scoring for vitiligo clinical trials. AI-powered measurement of depigmented skin across the body regions of the VASI from standardised photographs. CE-marked medical device.
