Microsoft Azure AI Fundamentals Computer Vision 1 — Questions and Answers
Question 1: Which Azure service provides pre-built APIs for image analysis, object detection, and OCR?
- Azure AI Language
- Azure AI Vision (Correct answer)
- Azure AI Speech
- Azure Bot Service
Correct answer: Azure AI Vision
Azure AI Vision (part of Azure Cognitive Services) offers pre-built APIs for analyzing images, detecting objects, reading text, and more.
Question 2: What does OCR stand for in the context of Azure AI Vision?
- Optical Character Recognition (Correct answer)
- Object Classification Routine
- Output Content Rendering
- Online Content Recognition
Correct answer: Optical Character Recognition
OCR stands for Optical Character Recognition, which is the ability to extract printed or handwritten text from images.
Question 3: Which Azure AI Vision feature can identify the dominant colors and overall mood of an image?
- Object detection
- Image analysis – color scheme (Correct answer)
- Spatial analysis
- Face detection
Correct answer: Image analysis – color scheme
The image analysis capability in Azure AI Vision includes color scheme detection, returning dominant foreground/background colors and an accent color.
Question 4: What is the purpose of Azure Custom Vision?
- Provide pre-built models for common vision tasks without training
- Allow users to train custom image classification and object detection models (Correct answer)
- Transcribe text from audio files
- Detect PII in documents
Correct answer: Allow users to train custom image classification and object detection models
Azure Custom Vision lets you train your own image classification and object detection models using your own labeled images without writing ML code.
Question 5: In Azure AI Vision, what is 'object detection' different from 'image classification'?
- Object detection only works on videos, classification works on images
- Object detection identifies and locates multiple objects with bounding boxes; classification assigns a single label to the whole image (Correct answer)
- Object detection requires custom training; classification uses pre-built models only
- Object detection returns text; classification returns coordinates
Correct answer: Object detection identifies and locates multiple objects with bounding boxes; classification assigns a single label to the whole image
Object detection finds and locates multiple objects in an image with bounding boxes, while image classification assigns a single category label to the entire image.
Question 6: Which Azure AI Vision feature generates a human-readable text description of an image?
- Spatial analysis
- Image captioning (Correct answer)
- OCR
- Face recognition
Correct answer: Image captioning
Image captioning in Azure AI Vision produces a natural language sentence that describes the content and context of an image.
