Show answer and explanation
Correct answer: C
Explanation
Azure Video Analyzer is the appropriate service for analyzing real-time video feeds, such as counting people entering a store and tracking recurring individuals. It is specifically designed for video analytics scenarios, whereas other services like the Computer Vision API, Face API, and Form Recognizer focus on different workloads like image analysis, facial recognition, and document processing.
- A. Incorrect.
The Computer Vision API is primarily designed for image analysis, such as detecting objects, extracting text, and providing image descriptions. While it can detect objects in images, it is not optimized for real-time video analysis or tracking individuals over time.
- B. Incorrect.
The Face API provides capabilities for facial recognition and analysis, including identifying individuals and detecting emotions. However, it is not designed to handle real-time video feeds for foot traffic analysis.
- C. Correct.
Azure Video Analyzer is the correct option because it provides real-time video analytics capabilities. It can process video feeds to count people, track their movements, and identify recurring individuals, which aligns with the requirements of the scenario.
- D. Incorrect.
Form Recognizer is used for extracting data from documents, such as invoices and receipts. It is unrelated to computer vision tasks involving video or people counting.
