Microsoft Azure AI Solution Exam: Face Service for Gender and Age Identification | Question Answered

Face Service Method for Finding Rectangular Face Coordinates or Locations

Question

Scenario: You are tasked to use face service in Azure to identify the gender and age of an individual in a given dataset.

You created a FaceClient object, and you plan to use the Face client library in C#

Which method would you call to find the rectangular face coordinates or locations? (choose one answer choice).

A. B. C. D.

Correct Answer: C.

Option A is incorrect because the GroupAsync method is used to divide faces into groups and hence does not meet the requirement criteria.

Option B is incorrect because the FindSimilarAsync method is used to find similar looking faces from an array of FaceIds.

It does not meet the requirement criteria either.

Option C is correct because the DetectWithUrlAsync and DetectWithStreamAsync methods can be used to get locations in an image.

Option D is incorrect because the IdentifyAsync method is used to find one to many closest matches of a specific face.

The correct method to call in order to find the rectangular face coordinates or locations using the Face client library in C# is the DetectWithUrlAsync method.

The DetectWithUrlAsync method is used to detect human faces in an image provided through a URL. When this method is called, it analyzes the image and returns a list of detected faces with their associated attributes such as age, gender, and face location.

The Face client library is a C# library that provides an easy-to-use interface for interacting with the Azure Face service. The library includes methods for detecting faces, verifying faces, identifying faces, and grouping faces.

However, the IdentifyAsync method is used for identifying a face against a set of known faces, whereas the GroupAsync method is used for grouping faces together based on their similarity. The FindSimilarAsync method is used to find similar faces to a given face within a specified face list.

Therefore, the correct method to call in order to find the rectangular face coordinates or locations in the given dataset using the Face client library in C# is the DetectWithUrlAsync method.
