AI-102 Implement computer vision solutions Practice Question
Your team is building a mobile app that uses Azure AI Computer Vision to extract text from business cards. The app must handle cards in multiple languages (English, French, German). Which feature of the Computer Vision API should you use?
⚠ Common exam trap
It's easy for candidates to confuse the legacy OCR API (option A) with the modern Read API, assuming they are interchangeable, but the Read API is the recommended service for document text extraction in the current Azure AI Computer Vision offering.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Read API
The Read API is the correct choice because it is the current, optimized version of the Computer Vision OCR service designed specifically for extracting printed and handwritten text from images of documents, including business cards. It supports multiple languages (English, French, German) and provides a higher accuracy and structured output (lines and words with bounding boxes) compared to the legacy OCR API. The Recognize Text operation is deprecated and should not be used for new solutions.
