How does Optical Character Recognition software work?

The OCR program recognizes characters in images or documents by performing an analysis of the image or document and recognizing the characters in it. At first, the OCR program analyzes the image or document, making it readable and distinguishing the text from the background, lines, etc. Then, it analyses each individual character and compares its shape with patterns of characters kept in its recognition system. After identifying the characters, the OCR software converts them into machine-readable text that can be edited, searched, copied, or stored digitally. This explains what is optical recognition and how it helps transform physical information into usable digital data. Modern OCR technologies allow processing different kinds of documents, for example, invoices, receipts, forms, books, and reports. Businesses often use OCR technologies for supporting document digitization, data extraction, and automated data entry. Thus, OCR can help save time and increase productivity by decreasing the necessity to type data manually. The result's accuracy may depend on such criteria as image quality, document format, font style, and printed or handwritten source. Source; https://dataqix.com/optical-character-recognition/
