A smart city initiative is implementing an Azure AI solution to monitor pedestrian flow in public squares. They need to count the number of people entering and exiting designated areas, detect congestion, and measure dwell time. Which Azure Computer Vision capability is designed for this purpose?
- AImage Analysis (Tags)
- BRead API
- CObject Detection
- DSpatial Analysis
Show answer & explanationAnswer & explanation
Correct answer: D. Spatial Analysis
Azure Computer Vision's Spatial Analysis is specifically designed for analyzing real-time video streams to detect the presence of people, track their movement, count entries/exits from defined zones, and measure dwell time.
Why the other options are wrong
- A. Image Analysis (Tags) provides general descriptive tags for static images.
- B. Read API extracts text from images, which is irrelevant for pedestrian flow.
- C. Object Detection identifies objects in images but doesn't track movement or flow.
Computer Vision Spatial Analysis
An Azure Computer Vision capability that analyzes real-time video streams to detect the presence of people, track their movement, and generate insights about their behavior in physical spaces.
- Counts people entering/exiting zones
- Measures dwell time
- Detects congestion and social distancing violations
- Processes video streams from cameras
Memory trick: Spatial Analysis makes sense of the crowd's dance.
