The Read API of the Computer Vision cognitive service in Azure is a powerful tool that allows you to extract printed and handwritten text from images and documents. Here are the statements given and their corresponding explanations:
A. Get Read Result operation fetches text from documents in a single step. This statement is true. The Read API offers a single-step operation for extracting text from images, which is the Get Read Result operation. This operation takes an image as input and returns the recognized text as output.
B. The Read API supports around 23 languages for printing text. This statement is also true. The Read API supports optical character recognition (OCR) for around 23 languages for printed text, including English, Spanish, Chinese, French, and German, among others. It also supports handwriting recognition for a smaller set of languages.
C. Supported file formats by the Read API are PDF, BMP, JPEG, PNG and TIF. This statement is true. The Read API supports several image file formats, including PDF, BMP, JPEG, PNG, and TIF. These formats are commonly used for storing scanned documents and images.
D. Up to 2000 pages can be processed for PDF file format while using the Read API. This statement is false. While the Read API does support PDF files, it has a limit of 50 pages per document. This means that if you have a PDF document with more than 50 pages, you will need to split it into smaller files before using the Read API to extract text.
E. The Read API can only support dimensions up to 10000x10000 pixels. This statement is true. The Read API has a limit on the size of the input image, which is currently set to 10000x10000 pixels. If your image is larger than this, you will need to resize it before passing it to the Read API.
In summary, the Read API of the Computer Vision cognitive service in Azure is a powerful tool for extracting text from images and documents. It supports several file formats, multiple languages, and offers a single-step operation for extracting text. However, it has limitations on the size of the input image and the number of pages per PDF document.
