In-scanner document image processing
First Claim
1. A method comprising:
- receiving a document image from an imaging device of a scanner;
determining a type of the document of the document image from a plurality of possible document types, the document type is determined by comparing parameters of document-type profiles stored in a memory of the scanner, all document type profile including;
document-type identifying parameters including definitions of a plurality of shapes, text, symbols, alphanumeric patterns, and relative proportions of two or more features; and
document-type processing parameters;
processing the document image to obtain document metadata;
adding the document image and metadata representative of the document metadata and document type to a data structure;
adding transaction-related metadata to the data structure; and
storing the data structure.

Abstract
Various embodiments herein each include at least one of systems, methods, data structures, and software for document image processing within a device such as a retail scanner. One such embodiment, in the form of a method, includes receiving a document image from an imaging device of a scanner and determining a type of the document represented in the document image. The document image may then be processed to obtain document metadata and the document image and metadata representative of the document metadata and document type are added to a data structure. This method may further include adding transaction-related metadata to the data structure. The data structure may then be stored on the scanner, transmitted via local communications link to a host device, transmitted via a network to a database for storage, or transmitted via a network to another system for one or both of processing and storage.

9. A method comprising:
- scanning each of a plurality of documents presented on a scanning surface of a scanner to obtain document images;
determining a type of each document of each document image from a plurality of possible document types, a document type is determined by comparing parameters of document-type profiles stored in a memory of the scanner, all document profile including;
document-type identifying parameters including definitions of a plurality of shapes, text, symbols, alphanumeric patterns, and relative proportions of two or more features; and
document-type processing parameters;
processing each document image to obtain a set of respective document metadata;
adding each document image and each respective set of document metadata including data representative of the respective document type to a data structure; and
storing the data structure. - View Dependent Claims (10, 11, 12, 13)
