AI-102 Question 107
Select 2You are building an AI solution that needs to detect objects in images and generate descriptive tags for those objects. You decide to use Azure Cognitive Services. Which steps should you take to achieve this functionality?
- A
Use the Computer Vision API to analyze the image and extract tags.
- B
Use the Face API to identify objects and generate tags.
- C
Specify the 'visualFeatures' parameter when calling the Computer Vision API to include 'Tags' and 'Objects'.
- D
Train a custom model using Azure Custom Vision to detect objects and generate tags.
- E
Enable the Image Analysis feature in Azure's Form Recognizer to automatically generate tags.
Show answer and explanation
Correct answers: A, C
Explanation
To detect objects and generate image tags, the Azure Computer Vision API provides prebuilt capabilities that simplify the process. By using the 'visualFeatures' parameter, you can specify which features to include, such as 'Tags' and 'Objects'. Other services like the Face API and Form Recognizer are not designed for object detection and tagging. Custom Vision is only needed for custom object detection scenarios, which is not required in this case.
- A. Correct.
Correct. The Computer Vision API is specifically designed to analyze images and can extract tags based on the visual content.
- B. Incorrect.
Incorrect. The Face API is designed for facial recognition, not for detecting objects or generating image tags.
- C. Correct.
Correct. The 'visualFeatures' parameter in the Computer Vision API allows you to specify features like 'Tags' and 'Objects' to include in the analysis.
- D. Incorrect.
Incorrect. While Azure Custom Vision can be used to train a custom model, it is not necessary for generating standard tags and detecting objects using Azure's prebuilt capabilities.
- E. Incorrect.
Incorrect. Form Recognizer is used for processing and analyzing structured and semi-structured documents, not for analyzing images to generate tags.
