In other words, OCR systems transform a two-dimensional image of text that could contain machine printed or handwritten text from its image representation into machine-readable text. OCR as a process generally consists of several sub-processes to perform as accurately as possible.

Google Document-AI: (Document AI Solution) Document AI or Document Intelligence is a technology that uses natural language processing (NLP) and machine learning (ML) to train computers to simulate a human review of documents. NLP enables the computer to understand the contents of documents, including the contextual nuances of the language within them, before extracting the information and insights contained in the documents. The technology can then categorize and organize the documents themselves. Document AI is used to process and intelligently parse forms, tables, receipts, invoices, tax forms, contracts, loan agreements, financial reports etc. Document AI utilizes machine learning to extract information from documents in digital and print forms. It supports over 200 languages.
