How to implement Azure Vision API for Text Extraction

Azure Computer Vision includes Optical Character Recognition (OCR) capabilities. You can use the Read API to extract printed and handwritten text from images and documents. It uses deep learning based models and works with text on a variety of surfaces and backgrounds. These include business documents, invoices, receipts, posters, business cards, letters, and whiteboards. The OCR APIs support extracting printed text in several languages.
