A. B. C. D.B
https://docs.microsoft.com/en-us/azure/cognitive-services/face/overviewTo analyze the images and ensure that only the photos that meet the requirements are retweeted, we can use the Cognitive Services APIs provided by Microsoft Azure.
In this scenario, we need to identify the faces in the images and determine whether or not they are wearing sunglasses.
Option A - the Verify operation in the Face service: The Verify operation in the Face service is used to compare two faces to determine if they belong to the same person. It is not suitable for this scenario because we need to analyze multiple faces in an image, not compare two faces.
Option B - the Detect operation in the Face service: The Detect operation in the Face service is used to detect faces in an image and extract facial features such as age, gender, and emotions. It also returns information about whether the face is wearing glasses or not. This operation can be used to identify the faces in the images and determine if they are wearing sunglasses. Therefore, Option B is a suitable choice for this scenario.
Option C - the Describe Image operation in the Computer Vision service: The Describe Image operation in the Computer Vision service is used to generate a textual description of the contents of an image, including objects, people, and their attributes. It is not suitable for this scenario because we need to analyze whether or not people are wearing sunglasses, which is not a standard attribute returned by this operation.
Option D - the Analyze Image operation in the Computer Vision service: The Analyze Image operation in the Computer Vision service is used to extract rich information from an image, including objects, people, text, and their attributes. This operation can be used to identify the faces in the images and determine if they are wearing sunglasses. Therefore, Option D is also a suitable choice for this scenario.
In summary, both the Detect operation in the Face service (Option B) and the Analyze Image operation in the Computer Vision service (Option D) can be used to analyze the images and meet the requirements of the scenario.
