Doctor Prescription Reader Technical Guide

What this tool does

This doctor prescription reader converts handwritten text from images into digital format. It employs optical character recognition to extract text segments and validates identified medical terms against the RxNorm pharmaceutical database.

How to use it

• Image file: JPG or PNG format.
• File size limit: 5MB per upload.
• Security: Cloudflare Turnstile verification required.

• Raw text: Digitized character string from input image.
• Validated medications: Terms matched to RxNorm records.
• Confidence scores: Percentage indicating match probability for each term.

Underlying logic / algorithm

The doctor handwriting reader uses a multi stage processing pipeline:

1. Preprocessing: Histogram equalization and thresholding for contrast optimization.
2. Text Detection: Regional analysis to locate handwriting areas within the frame.
3. Character Recognition: Sequence to sequence modeling to translate visual segments into digital text.
4. Nomenclature Validation: Fuzzy string matching against RxNorm database for medicine identification.

Limitations & scope

• Does not provide medical diagnosis or individual treatment recommendations.
• Does not replace the professional judgment of a pharmacist or physician.
• Accurately identifies text only; does not evaluate drug interactions, contraindications, or dosage appropriateness.
• Performance is dependent on image resolution and handwriting legibility.
• All identified medications must be manually verified against the physical prescription.
