Which Amazon service is specifically designed for computer vision tasks?

1. Amazon Comprehend

2. Amazon Rekognition

3. Amazon Lex

4. Amazon Polly

The correct answer is: Amazon Rekognition

Amazon Rekognition is designed specifically for computer vision tasks, making it the best choice in this context. This service offers powerful image and video analysis capabilities, allowing users to identify objects, people, text, scenes, and activities, as well as detect faces and compare them. It can also be used to analyze and index visual content for applications such as multimedia search, security monitoring, and user engagement analysis. In contrast, the other services mentioned serve different purposes. Amazon Comprehend is centered around natural language processing, enabling the extraction of insights from text through sentiment analysis, entity recognition, and topic modeling. Amazon Lex focuses on building conversational interfaces like chatbots, utilizing speech recognition and natural language understanding. Amazon Polly is a text-to-speech service that converts text into lifelike speech, designed for applications requiring verbal communication rather than visual analysis. Each of these services excels in its specific domain, but for computer vision tasks, Amazon Rekognition is the appropriate choice.
