Separation and Extraction of Valuable Information From Digital Receipts Using Google Cloud Vision OCR.
Automatization is a desirable feature in many business areas. Manually extracting information from a physical object such as a receipt is something that can be automated to save resources for a company or a private person. In this paper the process will be described of combining an already existing...
