Learn how the Computer Vision service can help you analyze images and extract text and objects with OCR and image analysis features. Find out which tasks can be performed by using this service and which tasks require other services.
Question
Which two tasks can be performed by using the Computer Vision service?
Select all that apply.
A. Extract text from scanned documents
B. Extract written text from an image
C. Detect objects in an image.
D. Translate the text in an image
Answer
B. Extract written text from an image
C. Detect objects in an image.
Explanation
The correct answer is B and C. The Computer Vision service can perform both tasks of extracting written text from an image and detecting objects in an image.
The Computer Vision service is a cloud-based service that provides developers with access to advanced algorithms for processing images and returning information. By uploading an image or specifying an image URL, Computer Vision algorithms can analyze visual content in different ways based on inputs and user choices.
One of the features of the Computer Vision service is optical character recognition (OCR), which can extract printed and handwritten text from images with mixed languages and writing styles. OCR can be used to read text from scanned documents, business cards, receipts, signs, and other sources. OCR can also translate the text in an image to a different language, if specified by the user.
Another feature of the Computer Vision service is image analysis, which can detect, classify, caption, and generate insights from images. Image analysis can identify objects, faces, colors, landmarks, celebrities, and other elements in an image. Image analysis can also perform tasks such as smart cropping, background removal, and content moderation.
Therefore, the Computer Vision service can perform both tasks of extracting written text from an image (B) and detecting objects in an image ©, but not the tasks of extracting text from scanned documents (A) or translating the text in an image (D). These tasks can be performed by using other services, such as Azure Cognitive Search or Translator.
