AI-900 Practice Question: Describe features of computer vision workloads on Azure
What is 'retail intelligence' using computer vision and what business value does it provide?
⚠ Common exam trap
Watch out — candidates often confuse computer vision with other AI workloads like recommendation engines or NLP, assuming any retail AI is 'retail intelligence' without recognizing the specific visual data source.

Correct answer & explanation
✓
Using store video to analyse traffic flow, dwell time, queue length, and planogram compliance
Retail intelligence using computer vision involves analyzing video feeds from in-store cameras to extract actionable insights such as customer traffic flow, dwell time at shelves, queue lengths, and planogram compliance. This is a classic computer vision workload on Azure, often implemented using Azure Video Indexer or Custom Vision, which processes visual data rather than transactional or textual data.

For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
AI that recommends products to online shoppers based on browsing history
Why it's wrong here
Recommender systems that suggest products from browsing history typically use collaborative filtering or content-based algorithms on clickstream and purchase data to personalize online shopping. This is e-commerce AI, operating on digital behavioral signals, whereas retail intelligence specifically processes physical store video to derive spatial insights. Because no camera footage or video analytics is involved, this option is not an example of retail intelligence.
- ✓
Using store video to analyse traffic flow, dwell time, queue length, and planogram compliance
Why this is correct
Retail intelligence in Azure is implemented through computer vision services such as Azure AI Vision Spatial Analysis, which detects and tracks people in store camera feeds to measure traffic flow, dwell time, queue length, and planogram compliance. The system runs video frames through object detection and tracking algorithms to compute aggregate metrics about shopper behavior and store conditions. This matches the exact definition of retail intelligence, which brings online-analytics-style data richness to brick-and-mortar stores.
- ✗
An AI system that processes retail POS transaction data to forecast sales
Why it's wrong here
Forecasting sales from POS transaction data is a time-series prediction problem, typically solved with regression or autoregressive models, not with computer vision. Retail intelligence, by contrast, centers on analyzing video from physical store environments, extracting insights like footfall patterns and shelf compliance. Since this option processes transactional numeric data rather than visual imagery, it does not align with the video-based retail intelligence workflow.
- ✗
Sentiment analysis of customer reviews from retail websites to improve products
Why it's wrong here
Sentiment analysis applies natural language processing (NLP) to text-based customer reviews, classifying opinions as positive, negative, or neutral to guide product improvements. This is fundamentally different from retail intelligence, which relies on computer vision models analyzing live or recorded video feeds from physical stores, not on textual input. Therefore, while it is a valid AI use case in retail, it does not match the Microsoft Azure retail intelligence pattern described in the question.
