Microsoft Azure AI Fundamentals — Question 142

You are processing photos of runners in a race.
You need to read the numbers on the runners' shirts to identity the runners in the photos.
Which type of computer vision should you use?

Answer options

• A. facial recognition
• B. optical character recognition (OCR)
• C. image classification
• D. object detection

Correct answer: B

Explanation

The correct answer is B, optical character recognition (OCR), as it is specifically designed to read and convert text from images into a machine-readable format. The other options, such as facial recognition and image classification, are not suitable for extracting textual information from images, while object detection focuses on identifying and locating objects but does not necessarily interpret characters.
