Abstract

An image correction system comprises a processor adapted to receive an image. The system also comprises a modifier accessible by the processor and adapted to automatically modify the image to replace a closed eye of a subject within the image with an open eye.

Claims

1. An image correction system, comprising:

a processor adapted to receive an image;

a detector configured to automatically detect a closed eye of a subject within the image; and

a modifier accessible by the processor and adapted to automatically modify the image to replace the closed eye within the image with an open eye.

2. The system of claim 1, wherein the detector is adapted to determine a characteristic of an eyelash line of the subject to detect the closed eye.

3. The system of claim 1, wherein the modifier is adapted to replace the closed eye with the open eye having a characteristic associated with the group consisting of gender characteristics, color characteristics, and ethnicity characteristics.

4. The system of claim 1, further comprising a locator accessible by the processor and adapted to automatically locate a face of the subject within the image.

5. The system of claim 1, wherein the detector is configured to determine at least one facial characteristic associated with the subject.

6. The system of claim 5, wherein the modifier is adapted to replace the closed eye using the facial characteristic.

7. The system of claim 1, wherein the modifier is adapted to apply a color characteristic associated with the open eye.

8. The system of claim 1, wherein the modifier is adapted to apply an iris color to the open eye.

9. The system of claim 1, wherein the modifier is adapted to apply a flesh tone color characteristic associated with the open eye.

10. The system of claim 1, wherein the modifier is further adapted to select the open eye from a library.

11. A method for image correction, comprising:

receiving an image comprising at least one subject;

automatically detecting a closed eye of a subject within the image; and

automatically modifying the image to replace the closed eye with an open eye.

12. The method of claim 11, wherein detecting comprises detecting an eyelash line of the closed eye.

13. The method of claim 11, further comprising automatically detecting a face of the subject within the image.

14. The method of claim 11, further comprising selecting the open eye from a library.

15. The method of claim 11, further comprising detecting at least one facial characteristic associated with the subject.

16. The method of claim 11, further comprising applying a characteristic to the open eye selected from the group consisting of gender characteristics, color characteristics, and ethnicity characteristics.

17. The method of claim 11, further comprising applying an iris color to the open eye.

18. The method of claim 11, further comprising applying a flesh tone corresponding to the subject to skin portions adjacent to the open eye.

19. An image correction system, comprising:

a library comprising at least one image of an open eye;

a detector accessible by a processor and configured to automatically detect a closed eye of a subject within an image based at least in part on an eyelash line of the subject; and

a modifier accessible by the processor and adapted to replace the closed eye on the subject with at least one the image of the open eye.

20. The system of claim 19, wherein the image of the open eye comprises a characteristic selected from the group consisting of gender characteristics, color characteristics, and ethnicity characteristics.

21. The system of claim 19, wherein the modifier is adapted to apply a color characteristic to the image of the open eye.

22. The system of claim 21, wherein the color characteristic comprises an iris color.

23. The system of claim 21, wherein the color characteristic comprises a flesh tone associated with a skin portion of the subject adjacent the open eye.

24. The system of claim 19, wherein the modifier is adapted to modify a size of the open eye corresponding to a facial direction of the subject.

25. An image correction system, comprising:

means for receiving an image having at least one subject;

means for automatically detecting a closed eye of the at least one subject within the image; and

means for modifying the image to replace the closed eye with an open eye.

26. The system of claim 25, further comprising means for automatically locating a face of the subject within the image.

27. The system of claim 25, wherein the detecting means comprises means for automatically identifying an eyelash line corresponding to the closed eye.

28. The system of claim 25, further comprising means for applying a characteristic to the open eye selected from the group consisting of gender characteristics, color characteristics, and ethnicity characteristics.

29. The system of claim 25, further comprising means for sizing the open eye corresponding to a facial direction of the subject within the image.

30. The system of claim 25, further comprising means for detecting at least one facial characteristic associated with the subject.

31. The system of claim 30, further comprising means for modifying the image using the facial characteristic.

32. The system of claim 25, further comprising means for retrieving an image of the open eye from a library.
