Description

Upon a user-initiated request to perform a severity analysis on an ingested image, the system shall execute the Automatic Urticaria Activity Score (AUAS) assessment. The system shall perform the following integrated actions:

1. Calculate clinical signs: Invoke the AUAS model to analyze the image and combine the visual signs with user-provided subjective data:
   • Visual signn (from image analysis): The system shall detect and count the total number of wheals. Based on this count, it determines the corresponding wheals score (from 0-3).
   • Subjective Symptom (from user input): The system shall incorporate the provided score for pruritus (itch severity, from 0-3).
   • Final Score: The system shall calculate the final, composite AUAS score using those clinical signs.
2. Compute UAS score and its corresponding interpretation using the calculated clinical scores.
3. Generate visual evidence: Create an annotated image by overlaying bounding boxes on the original input image. These boxes shall highlight each individual wheal detected by the model during the analysis.
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 UAS score and its corresponding clinical interpretation band (e.g., "Well-controlled," "Moderate," "Severe").
   • The component scores and interpretations for both wheals and pruritus.
   • The total number of wheals counted.
   • The annotated visual evidence image generated in step 2.
