Microsoft Azure AI Fundamentals (AI-900)Describe features of computer vision workloads on AzureMedium
A construction company wants to monitor worker safety on job sites. They need a computer vision system that can identify if workers are wearing appropriate personal protective equipment (PPE) like hard hats and safety vests. The system should be able to locate each piece of PPE on individual workers in real-time video feeds. Which computer vision capability is required for this task?
- AOptical Character Recognition (OCR)
- BImage Classification
- CImage Captioning
- DObject Detection
Show answer & explanationAnswer & explanation
Correct answer: D. Object Detection
Object Detection is required because it can identify and locate multiple distinct objects (hard hats, safety vests) within an image or video frame by drawing bounding boxes around them, which is essential for verifying PPE compliance on individual workers.
Why the other options are wrong
- A. OCR is for extracting text, not for identifying visual objects like PPE.
- B. Image Classification would only tell if an image generally contains PPE, not where it is or if each worker is wearing it.
- C. Image Captioning generates textual descriptions of an image, which is not suitable for locating specific items of PPE.
Object Detection for PPE
Using object detection models to automatically identify and locate personal protective equipment (PPE) like hard hats and vests on individuals in images or video.
- Draws bounding boxes around each detected PPE item.
- Can be trained for various types of PPE.
- Enables automated safety monitoring in industrial settings.
Memory trick: Detect objects with bounding boxes.
