AI-102 Question 128
Select 3You are tasked with creating a solution that extracts handwritten text from scanned documents using Azure AI Vision. After configuring an OCR (Optical Character Recognition) model in Azure AI Vision, which of the following steps must you take to successfully convert handwritten text into digital format?
- A
Use the Azure AI Vision Read API to analyze the document and retrieve the handwritten text.
- B
Ensure that the document is in a supported image format or a PDF before submitting it to the Azure AI Vision service.
- C
Train a custom model in Azure AI Vision specifically for handwritten text recognition.
- D
Parse the JSON response returned by the Azure AI Vision API to extract the detected handwritten text.
- E
Use the Azure Form Recognizer service instead of Azure AI Vision for handwritten text extraction.
Show answer and explanation
Correct answers: A, B, D
Explanation
To extract handwritten text using Azure AI Vision, you need to use the Azure AI Vision Read API, ensure the document is in a supported format for processing, and parse the JSON response to get the detected text. Training a custom model is unnecessary as the Azure AI Vision OCR already includes pre-trained capabilities for handwriting. Using Azure Form Recognizer is not required for this use case as the Azure AI Vision service is sufficient.
- A. Correct.
This is correct. The Azure AI Vision Read API is designed to analyze documents, including handwriting, and retrieve the text in digital format.
- B. Correct.
This is correct. The Azure AI Vision service supports specific formats like images (JPEG, PNG) and PDFs, so ensuring the document is in a supported format is a required step.
- C. Incorrect.
This is incorrect. Pre-trained OCR models in Azure AI Vision are capable of recognizing handwritten text without the need for training a custom model.
- D. Correct.
This is correct. The Azure AI Vision API returns output in JSON format, so parsing the JSON response is necessary to extract the detected text.
- E. Incorrect.
This is incorrect. While Azure Form Recognizer can handle certain types of text extraction, Azure AI Vision is the appropriate service for generic handwritten text recognition tasks using OCR.
