Abstract
Abstract A computer program product for detecting eye color defects of a subject in an image due to flash illumination comprises : a computer readable storage medium having a computer program stored thereon for performing the steps of detecting skin colored regions in a digital image; searching the skin colored regions for groups of pixels with color characteristic of redeye defect; and correcting color of the pixels based on a location of redeye defect found in step (b).

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
80 words
A computer program product for detecting eye color defects of
a subject in an image due to flash illumination, comprising : a computer readable
storage medium having a computer program stored thereon for performing the
steps of: (a) detecting skin colored regions in a digital image; (b) searching the skin colored regions for groups of pixels with color
characteristic of redeye defect; and (c) correcting color of the pixels based on a location of redeye defect
found in step (b).
Claim 2
Dependent Claim
41 words
The computer program product as in claim 1, wherein step (a)
includes: (a1) segmenting the digital image into continuous regions of
uniform color and assigning a score indicating probability that the region
corresponds to skin for forming a candidate skin region.
Claim 3
Dependent Claim
29 words
The computer program product as in claim 2, wherein step (a1)
includes merging two or more candidate skin regions based on their similarity of
color and degree of connectivity.
Claim 4
Dependent Claim
25 words
The computer program product as in claim 2, wherein step (a1)
includes determining probability that the candidate region is a face based on its
shape.
Claim 5
Dependent Claim
92 words
A computer program product for detecting eye color defects of
a subject in an image due to flash illumination, comprising : a computer readable
storage medium having a computer program stored thereon for performing the
steps of: (a) searching of a digital image for groups of pixels with color
characteristic of redeye defect for forming candidate redeye defect; (b) determining whether the candidate redeye defect is located at a
position that matches an eye; and (c) correcting color of the pixels based on a location of redeye defect
found in step (b).
Claim 6
Dependent Claim
46 words
The computer program product as in claim 5, wherein the
match of step (b) further includes determining for a pair of candidate redeye
defects the size and tilt expected of an eye based on distance between and the tilt
of the pair of candidate redeye defects.
Claim 7
Dependent Claim
27 words
The computer program product as in claim 5, wherein the
match of step (b) includes correlating a region around the candidate redeye
defects with an eye template.
Claim 8
Dependent Claim
30 words
The computer program product as in claim 7, wherein the
match of step (b) includes correlating the region around the candidate redeye
defects with individual zones of the eye template.
Claim 9
Dependent Claim
99 words
A computer program product for detecting eye color defects of
a subject in an image due to flash illumination, comprising : a computer readable
storage medium having a computer program stored thereon for performing the
steps of: (a) detecting skin colored regions in a digital image; (b) searching the skin colored regions for groups of pixels with color
characteristic of redeye defect for forming a candidate redeye defect; (c) determining whether the candidate redeye defect is located at a
position that matches an eye; and (d) correcting color of the pixels based on a location of the redeye defect.
