AI-102 Implement computer vision solutions Practice Question
Which TWO Azure services can be used to perform optical character recognition (OCR) on images?
⚠ Common exam trap
Candidates may mistakenly think that only the Computer Vision Read API can perform OCR. However, Azure Form Recognizer also uses OCR technology to extract text from documents, though it is optimized for structured forms and tables. The correct answers are both A and E. A common mistake is to choose the Face API or Custom Vision, which do not provide OCR capabilities.
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
✓
Azure Computer Vision Read API
Azure Computer Vision Read API is correct because it provides a dedicated OCR capability that extracts printed and handwritten text from images and documents. It uses deep learning models to detect text regions, recognize characters, and return structured output with bounding boxes and confidence scores.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Azure Computer Vision Read API
Why this is correct
The Computer Vision Read API is purpose-built for OCR, extracting printed and handwritten text from images and documents via synchronous or asynchronous read operations. This directly satisfies the stem's requirement for an Azure service performing optical character recognition on images.
- ✗
Azure Face API
Why it's wrong here
Azure Face API performs face detection, verification and recognition; it does not return text from images. It is tempting because it processes images and can detect attributes, but OCR requires Azure AI Vision's Read model or Azure AI Document Intelligence, which extract printed and handwritten text.
- ✗
Azure Video Indexer
Why it's wrong here
Video Indexer extracts OCR text only as part of video/audio insight pipelines, requiring uploaded video assets rather than still images. It is tempting because it does surface on-screen text, but that is a byproduct of media indexing; for standalone image OCR you would use Azure AI Vision's Read API instead.
- ✗
Azure Custom Vision
Why it's wrong here
Custom Vision trains image classification and object detection models on labelled samples; it outputs predicted tags or bounding boxes, never transcribed text. It is tempting because it processes images, but its purpose is custom visual recognition; OCR of images belongs to Azure AI Vision's Read API.
- ✓
Azure Form Recognizer
Why this is correct
Azure Form Recognizer performs OCR as part of its document analysis pipeline, extracting printed and handwritten text from images and PDFs before returning structured fields. This satisfies the stem's requirement for an Azure service capable of optical character recognition on images.
