Question
You are building an image tagging solution for social media, that tags your friends automatically in images. Which Azure Cognitive Services service should you use?
A. Computer Vision.
B. Text Analytics.
C. Face.
D. Form Recognizer.
Answer
C. Face.
Explanation
To automatically tag friends in social media images, the best Azure Cognitive Service to use is the Face service. The Face service has capabilities specifically designed for detecting, identifying, analyzing and tagging human faces in images.
Key features that make the Face service ideal for this scenario:
- Face Detection: Detects the presence and location of human faces in an image
- Face Verification: Compares two faces to determine if they belong to the same person
- Face Identification: Matches detected faces against a database of known faces/people
- Face Grouping: Groups faces in an image by their visual similarity, useful for identifying multiple occurrences of the same person
With the Face service, you can build a known persons/friends database by registering faces from sample images. Then when a new social media image is uploaded, the Face service can detect any faces present, match them against the known persons database, and automatically tag the identified friends.
The other options are less suitable because:
- Computer Vision: While it can detect faces, it lacks specific capabilities for identifying individuals
- Text Analytics: Focused on analyzing text data, not images/faces
- Form Recognizer: Specializes in extracting data from forms/documents, not identifying people in images
So in summary, the Face service provides the key capabilities needed (face detection, identification, matching) to automatically recognize and tag friends’ faces in social media images, making it the best choice for this AI-900 exam question.
The Face service in Azure Cognitive Services is specifically designed for recognizing and identifying human faces in images. It can be used to automatically tag friends in social media images by detecting and recognizing their faces.
