US 2009/0214085 A1 · REDUCTION OF INCORRECTLY IDENTIFIED DOCUMENT SCANNING DEFECTS

Abstract

In general, this disclosure describes techniques of reducing the possibility of an image evaluation device incorrectly identifying defects in images of documents. Some defects may be apparent in the images of both sides of a document. For instance, a tear in a document could be apparent in an image of a front side and an image of a rear side of the document. However, the image evaluation device could erroneously identify such a tear in an image of one side of the document. In this case, the tear would not be apparent in the image of the other side of the document. To reduce the possibility that the image evaluation device erroneously identifies such a defect, the image evaluation device may determine whether defects identified in the image of the front side of the document correspond to defects identified in the image of the rear side of the document.

Dependent claims

A method comprising:

receiving a first image, wherein the first image is a digital image of a front surface of a document;
receiving a second image, wherein the second image is a digital image of a rear surface of the document;
identifying defects in the first image that could hinder use of the first image and the second image to process the document in an automated document processing system;
identifying defects in the second digital image that could hinder use of the first image and the second image to process the document in the automated document processing system;
determining whether a first defect corresponds to any of the defects in the second image, wherein the first defect is one of the identified defects in the first image;
and
outputting data that indicates that the first image and the second image include a defect that could hinder use of the first image and the second image in the automated document processing system when the first defect corresponds to one of the defects in the second image.

4 more elements

A system that comprises an image evaluation device that includes:

a front defect detection module that identifies defects in a first image that could hinder use of a first image to process a document in an automated electronic document processing system, wherein the first image is a digital image of a front surface of the document;
a rear defect detection module that identifies defects in a second image that could hinder use of the second image to process the document in the automated electronic document processing system, wherein the second image is a digital image of a rear surface of the document;
a defect correspondence module that determines whether a first defect corresponds to any of the defects in the second image, wherein the first defect is one of the identified defects in the first image;
and
an output module that outputs data that indicates that the first image and the second image include a defect that could hinder use of the first image and the second image in the automated document processing system when the first defect corresponds to one of the defects in the second image.

2 more elements

A computer-readable medium comprising instructions that, when executed by one or more processors, cause the one or more processors to:

receive a first image, wherein the first image is a digital image of a front surface of a document;
receive a second image, wherein the second image is a digital image of a rear surface of the document;
identify defects in the first image that could hinder use of the first image and the second image to process the document in an automated document processing system;
identify defects in the second digital image that could hinder use of the first image and the second image to process the document in the automated document processing system;
determine whether a first defect corresponds to any of the defects in the second image, wherein the first defect is one of the identified defects in the first image;
and
generate data that indicates that the first image and the second image include a defect that could hinder use the first image and the second image in the automated document processing system when the first defect corresponds to one of the defects in the second image.
