You send an image to an Azure AI Vision API and receive back the annotated image shown in the following exhibit.Which type of computer vision was used?
Answer(s): A
Object detection is similar to tagging, but the API returns the bounding box coordinates (in pixels) for each object found. For example, if an image contains a dog, cat and person, the Detect operation will list those objects together with their coordinates in the image. You can use this functionality to process the relationships between the objects in an image. It also lets you determine whether there are multiple instances of the same tag in an image.The Detect API applies tags based on the objects or living things identified in the image. There is currently no formal relationship between the tagging taxonomy and the object detection taxonomy. At a conceptual level, the Detect API only finds objects and living things, while the Tag API can also include contextual terms like "indoor", which can't be localized with bounding boxes.

What are two tasks that can be performed by using the Azure AI Vision service? Each correct answer presents a complete solution.Note: Each correct selection is worth one point.
Answer(s): B,C
B: Azure's Computer Vision service provides developers with access to advanced algorithms that process images and return information based on the visual features you're interested in. For example, Computer Vision can determine whether an image contains adult content, find specific brands or objects, or find human faces.C: Computer Vision includes Optical Character Recognition (OCR) capabilities. You can use the new Read API to extract printed and handwritten text from images and documents.Computer Vision is now Azure AI Vision.

What are two tasks that can be performed by using computer vision? Each correct answer presents a complete solution.Note: Each correct selection is worth one point.
B: Identify commercial brands in images or videos from a database of thousands of global logos. You can use this feature, for example, to discover which brands are most popular on social media or most prevalent in media product placement.C: Analyze color usage within an image. Computer Vision can determine whether an image is black & white or color and, for color images, identify the dominant and accent colors.

You need to build an image tagging solution for social media that tags images of your friends automatically.Which Azure AI service should you use?
The Azure Face service provides AI algorithms that detect, recognize, and analyze human faces in images.Facial recognition software is important in many different scenarios, such as identity verification, touchless access control, and face blurring for privacy.
