Question
What are two tasks that can be performed by using the Computer Vision service? Each correct answer presents a complete solution.
NOTE: Each correct selection is worth one point.
A. Train a custom image classification model.
B. Detect faces in an image.
C. Recognize handwritten text.
D. Translate the text in an image between languages.
Answer
B. Detect faces in an image.
C. Recognize handwritten text.
Explanation
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.
The correct answers are B. Detect faces in an image and C. Recognize handwritten text.
The Computer Vision service is a cloud-based service that provides developers with access to advanced algorithms for processing images and returning information. The service can perform various tasks, such as image analysis, text extraction, spatial analysis, and facial recognition.
Two of the tasks that can be performed by using the Computer Vision service are:
- Detect faces in an image: The service can locate and label human faces within an image, such as drawing bounding boxes around eyes or mouths. The service can also provide additional information about the faces, such as age, gender, emotion, hair color, and accessories.
- Recognize handwritten text: The service can extract printed and handwritten text from images with mixed languages and writing styles using optical character recognition (OCR) technology. The service can also preserve the text layout and structure, such as tables, paragraphs, and lines.
The other two options are not tasks that can be performed by using the Computer Vision service:
- Train a custom image classification model: The service does not offer the ability to train a custom image classification model. However, there is another service called Custom Vision that allows developers to create and train custom image classifiers with just a few images.
- Translate the text in an image between languages: The service does not offer the ability to translate the text in an image between languages. However, there is another service called Translator that can perform text translation for over 90 languages, including text extracted from images.
