OCR can be used to read text in photographs (for example, road signs or store fronts) or to extract information from scanned documents such as letters, invoices, or forms.

OCR is a technique that can identify and read text from images, such as scanned documents, photos, or screenshots. OCR converts the text in an image into a format that can be edited, searched, or analyzed by a computer. OCR can be used for various purposes, such as extracting information from forms, invoices, receipts, business cards, or ID cards.

Some of the Azure services that use OCR are:

  • Computer Vision: This service can analyze images and extract text, faces, objects, colors, and more. It can also generate captions and tags for images. Computer Vision provides a Read API that can perform OCR on images and return the text and its location in the image.
  • Form Recognizer: This service can extract key-value pairs and tables from forms, such as invoices, purchase orders, tax forms, or medical forms. Form Recognizer can also use OCR to read text from forms and convert it into structured data.
  • Azure Cognitive Search: This service can index and search data from various sources, such as databases, files, or web pages. Azure Cognitive Search can also use OCR to extract text from images and make it searchable.
