A retail company wants to analyze customer traffic patterns within its stores by tracking the movement of shoppers. The solution needs to identify individual customers as they walk through different departments without necessarily identifying their personal details. Which computer vision capability should be used to achieve this goal?
- AOptical Character Recognition (OCR)
- BObject Detection and Tracking
- CFacial Recognition
- DImage Classification
Show answer & explanationAnswer & explanation
Correct answer: B. Object Detection and Tracking
Object Detection and Tracking is the most appropriate capability. Object detection would identify individual shoppers (as 'person' objects), and tracking would then follow their movement paths over time, providing data on traffic patterns.
Why the other options are wrong
- A. OCR extracts text and is irrelevant to tracking people.
- C. Facial Recognition identifies *specific individuals* and is not required or necessarily desired for traffic pattern analysis, which focuses on anonymous movement.
- D. Image Classification labels an entire scene, not individual moving objects.
Object Tracking
A computer vision technique that follows the movement of detected objects across a sequence of frames in a video.
- Often used in conjunction with object detection.
- Enables analysis of trajectories, speed, and behavior.
- Crucial for surveillance, traffic analysis, and sports analytics.
Memory trick: To track movement, first detect, then follow.
