Discover the ideal Azure Cognitive Services solution for automating image tagging in social media, specifically targeting images of your friends. Explore the benefits and capabilities of Computer Vision, Face, Text Analytics, and Form Recognizer services. Unlock the power of AI-driven image recognition and tagging to streamline your social media experience.

Question

You need to build an image tagging solution for social media that tags images of your friends automatically. Which Azure Cognitive Services service should you use?

A. Computer Vision
B. Face
C. Text Analytics
D. Form Recognizer

Answer

B. Face

Explanation

The correct answer is B. Face.

Face is an Azure Cognitive Service that provides algorithms for detecting, recognizing, and analyzing human faces in images. You can use Face to identify and verify the identity of people in your images, as well as to detect emotions, age, gender, and other facial attributes. Face can also group faces based on their similarity and find similar faces across a collection of images.

For the image tagging solution for social media, you can use Face to tag images of your friends automatically by creating a person group that contains the faces and names of your friends. Then, you can use the Identify API to compare an input face with the faces in the person group and return the most similar ones. You can also use the Find Similar API to find faces that are similar to a query face in a large set of images.

Computer Vision is an Azure Cognitive Service that provides algorithms for analyzing the content of images and videos. You can use Computer Vision to extract text, generate captions, identify objects, detect faces, and more. However, Computer Vision does not provide the functionality of identifying and verifying specific people in images, which is required for the image tagging solution.

Text Analytics is an Azure Cognitive Service that provides algorithms for analyzing the language and sentiment of text. You can use Text Analytics to extract key phrases, detect languages, identify entities, and more. However, Text Analytics does not work with images, which is the input for the image tagging solution.

Form Recognizer is an Azure Cognitive Service that provides algorithms for extracting data and text from forms and documents. You can use Form Recognizer to analyze invoices, receipts, business cards, and more. However, Form Recognizer does not work with images that contain faces, which is the input for the image tagging solution.
