First Claim
Patent Images
1. A computer readable medium containing instructions which, when executed by a computer, perform a process comprising:
- receiving an image of a receipt;
preprocessing the image of the receipt in preparation for data extraction;
identifying the size of the receipt based on the image of the receipt;
resizing the image of the receipt when it is determined based on the size identification that resizing is necessary;

Abstract
Systems and methods of capturing data from mobile images of receipts implemented are provided herein. One of the most important tasks behind the mobile receipt capture technology is understanding and utilizing category-specific rules in the form of known document sizes, relationships between different document fields, etc. For example, knowledge that many receipts have 3 inch widths helps to alter an image to restore the actual size of a receipt, which in turn improves a printing function and, most importantly, accuracy of content extraction such as optical character recognition.
