Abstract
Abstract The present invention relates to systems and methods for identifying front pages from images representing media. In an embodiment, a system for identifying at least one front page within an image representing media is provided. The system includes a matcher, an aggregator and a reviewer. In another embodiment, a method for identifying at least one front page within an image representing media is provided. The method includes comparing each page to matching criteria to produce a matching confidence score. The method also includes aggregating, as front page candidates, each page having a matching confidence score that exceeds a matching confidence score threshold. The method further includes receiving decision information and identifying front pages from front page candidates based upon the decision information. According to another embodiment, the matching criteria may comprise at least one local, affine invariant feature point.

128 words
A system for identifying at least one front page within an image representing media having at least one page, comprising: a matcher configured to receive the image representing media having at least one page and electronically compare each page to at least one matching criterion to produce a matching confidence score for each page, wherein the at least one matching criterion comprises at least one feature point; an aggregator configured to aggregate, as front page candidates, each page having a matching confidence score that exceeds a matching confidence score threshold; a reviewer configured to receive decision information and identify the at least one front page from the front page candidates based upon the decision information; and an analysis continuity module configured to recalibrate the matching confidence score threshold.
Claim 3
Independent Claim
145 words
A system for identifying at least one front page within an image representing media having at least one page, comprising: a matcher configured to receive the image representing media having at least one page and electronically compare each page to at least one matching criterion to produce a matching confidence score for each page, wherein the at least one matching criterion comprises at least one feature point; an aggregator configured to aggregate, as front page candidates, each page having a matching confidence score that exceeds a matching confidence score threshold; a reviewer configured to receive decision information and identify the at least one front page from the front page candidates based upon the decision information; and a page dater configured to obtain a date from each identified front page and assign the date to the at least one page associated with the identified front page.
Claim 4
Independent Claim
145 words
A system for identifying at least one front page within an image representing media having at least one page, comprising: a matcher configured to receive the image representing media having at least one page and electronically compare each page to at least one matching criterion to produce a matching confidence score for each page, wherein the at least one matching criterion comprises at least one feature point; an aggregator configured to aggregate, as front page candidates, each page having a matching confidence score that exceeds a matching confidence score threshold; a reviewer configured to receive decision information and identify the at least one front page from the front page candidates based upon the decision information; and a page dater configured to obtain a date from each identified front page and assign the date to the at least one page associated with the identified front page.
Claim 5
Dependent Claim
102 words
A computer-implemented method of identifying at least one front page within an image representing media having at least one page, comprising: electronically comparing each page of the image to at least one matching criterion to produce a matching confidence score for each page, wherein the at least one matching criterion comprises at least one feature point; aggregating, as front page candidates, each page having a matching confidence score that exceeds a matching confidence score threshold; receiving decision information; identifying the at least one front page from the front page candidates based upon the decision information; and recalibrating the matching confidence score threshold.
Claim 6
Dependent Claim
102 words
A computer-implemented method of identifying at least one front page within an image representing media having at least one page, comprising: electronically comparing each page of the image to at least one matching criterion to produce a matching confidence score for each page, wherein the at least one matching criterion comprises at least one feature point; aggregating, as front page candidates, each page having a matching confidence score that exceeds a matching confidence score threshold; receiving decision information; identifying the at least one front page from the front page candidates based upon the decision information; and recalibrating the matching confidence score threshold.
Claim 7
Dependent Claim
119 words
A computer-implemented method of identifying at least one front page within an image representing media having at least one page, comprising: electronically comparing each page of the image to at least one matching criterion to produce a matching confidence score for each page, wherein the at least one matching criterion comprises at least one feature point; aggregating, as front page candidates, each page having a matching confidence score that exceeds a matching confidence score threshold; receiving decision information; identifying the at least one front page from the front page candidates based upon the decision information; obtaining a date from each identified front page; and assigning the date to the at least one page associated with the identified front page.
Claim 8
Dependent Claim
