The Azure AI Vision service (formerly Computer Vision) is designed to analyze visual content in images and videos. According to Microsoft Learn's "Describe features of computer vision workloads," Azure AI Vision can identify objects, people, text, and scenes, and even classify images or detect objects in real time.
Identifying breeds of animals in live video streams is an example of image classification or object detection- core capabilities of Azure AI Vision. The Vision service can analyze each frame in a video, recognize animals, and classify them according to known categories, making this the correct answer.
The other options are incorrect:
* B. Extracting key phrases from documents # Done by Azure AI Language (Text Analytics).
* C. Extracting data from handwritten letters # Done by Azure AI Document Intelligence (Form Recognizer) using OCR.
* D. Creating thumbnails for training videos # While possible in Azure Media Services, it's not a primary Azure AI Vision function.
Thus, the best answer is A. Identifying breeds of animals in live video streams.
