Description

Upon a user-initiated request to perform a severity analysis on an ingested image, the system shall execute the Automatic Eczema Area and Severity Index (AEASI) assessment. The system shall perform the following integrated actions:

1. Calculate clinical signs: Invoke the AEASI model to analyze the image and compute the following:
   • The quantitative scores for the affected surface area, redness, thickness, scratching, and lichenification.
2. Compute EASI score and its corresponding interpretation using the calculated clinical scores.
3. Generate visual evidence: Create a derivative image by overlaying a lesion mask on the original input image. This mask shall visually delineate the lesion areas identified by the model.
4. Assemble and present report: Generate and display a structured clinical report that consolidates the analysis results. The report shall contain the following clearly labelled data points:
   • The final EASI score and its corresponding clinical interpretation band (e.g., "Mild").
   • The individual component scores for all assessed clinical signs.
   • The visual evidence image generated in step 2.

Derived from PRS

• PRS-2ZB: Measure severity by combining image analysis and user-reported symptoms in scoring systems
