Abstract
Abstract A batch processing method for enhancing an appearance of a face located in a digital image, where the image is one of a large number of images that are being processed through a batch process, comprises the steps of: (a) providing a script file that identifies one or more original digital images that have been selected for enhancement, wherein the script file includes an instruction for the location of each original digital image; (b) using the instructions in the script file, acquiring an original digital image containing one or more faces; (c) detecting a location of facial feature points in the one or more faces, said facial feature points including points identifying salient features including one or more of skin, eyes, eyebrows, nose, mouth, and hair; (d) using the location of the facial feature points to segment the face into different regions, said different regions including one or more of skin, eyes, eyebrows, nose, mouth, neck and hair regions; (e) determining one or more facially relevant characteristics of the different regions; (f) based on the facially relevant characteristics of the different regions, selecting one or more enhancement filters each customized especially for a particular region and selecting the default parameters for the enhancement filters; (g) executing the enhancement filters on the particular regions, thereby producing an enhanced digital image from the original digital image; (h) storing the enhanced digital image; and (i) generating an output script file having instructions that indicate one or more operations in one or more of the steps (c)–(f) that have been performed on the enhanced digital image.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
193 words
A method for enhancing an appearance of a face located in a digital image, wherein the appearance includes one or more symmetrical features, said method comprising the steps of: (a) acquiring an original digital image containing one or more faces; (b) detecting a location of facial feature points in the one or more faces, said facial feature points including points identifying salient symmetrical features including one or more of skin, eyes, eyebrows, nose, mouth, and hair; (c) using the location of the facial feature points to segment the face into different regions, said different regions including one or more of skin, eyes, eyebrows, nose, mouth, neck and hair regions; (d) determining one or more facially relevant characteristics of the different regions; (e) based on the facially relevant characteristics of the different regions, selecting (1) one or more enhancement filters each customized especially for a particular region and (2) the default parameters for the enhancement filters; and (f) executing the enhancement filters on the particular regions in a proportional manner to account for symmetry between the facially relevant characteristics of the different regions, thereby producing an enhanced digital image from the original digital image.
Claim 2
Independent Claim
193 words
A method for enhancing an appearance of a face located in a digital image, wherein the appearance includes one or more symmetrical features, said method comprising the steps of: (a) acquiring an original digital image containing one or more faces; (b) detecting a location of facial feature points in the one or more faces, said facial feature points including points identifying salient symmetrical features including one or more of skin, eyes, eyebrows, nose, mouth, and hair; (c) using the location of the facial feature points to segment the face into different regions, said different regions including one or more of skin, eyes, eyebrows, nose, mouth, neck and hair regions; (d) determining one or more facially relevant characteristics of the different regions; (e) based on the facially relevant characteristics of the different regions, selecting (1) one or more enhancement filters each customized especially for a particular region and (2) the default parameters for the enhancement filters; and (f) executing the enhancement filters on the particular regions in a proportional manner to account for symmetry between the facially relevant characteristics of the different regions, thereby producing an enhanced digital image from the original digital image.
Claim 3
Dependent Claim
29 words
The method as claimed in claim 1 wherein the enhancement filters employed in step (f) either preserve symmetry or improve symmetry between facially relevant characteristics of the different regions.
Claim 4
Dependent Claim
20 words
A computer storage medium having instructions stored therein for causing a computer to perform the method of claim 1 .
Claim 5
Independent Claim
141 words
A method for enhancing the shape of symmetrical features appearing in a face located in a digital image, said method comprising the steps of: (a) acquiring a digital image containing one or more faces; (b) detecting a location of facial feature points in the one or more faces, said facial feature points including points identifying a pair of salient symmetrical features amenable to shape adjustment; (c) using the facial feature points to determine two or more source points that are positioned relative to the salient features; (d) using the facial feature points to determine two or more destination points which determine the desired change of the salient features; and (e) warping the shape of the salient feature by using the source points and the destination points in a manner that substantially equalizes changes in shape for the pair of symmetrical features.
Claim 6
Independent Claim
141 words
A method for enhancing the shape of symmetrical features appearing in a face located in a digital image, said method comprising the steps of: (a) acquiring a digital image containing one or more faces; (b) detecting a location of facial feature points in the one or more faces, said facial feature points including points identifying a pair of salient symmetrical features amenable to shape adjustment; (c) using the facial feature points to determine two or more source points that are positioned relative to the salient features; (d) using the facial feature points to determine two or more destination points which determine the desired change of the salient features; and (e) warping the shape of the salient feature by using the source points and the destination points in a manner that substantially equalizes changes in shape for the pair of symmetrical features.
