Microsoft Azure AI Fundamentals — Question 204

You have a security system that analyzes images from CCTV to provide authorized staff entry into restricted area.

Which type of computer vision does the system use?

Answer options

• A. optical character recognition (OCR)
• B. semantic segmentation
• C. facial detection and facial recognition
• D. image analysis

Correct answer: C

Explanation

The correct answer is C, as facial detection and facial recognition are specifically designed to identify and verify individuals' identities, making them suitable for security access control. Options A and B are not applicable because OCR focuses on text recognition and semantic segmentation deals with classifying each pixel in an image rather than identifying individuals. Option D, while related to image understanding, is too broad and does not specifically address recognizing faces.
