Patent Images
1. A system comprising:
- means for receiving an image;
means for searching a set of areas of the image for candidate pixels of one or more colors, wherein the one or more colors comprise colors corresponding to red-eye;
means for combining the candidate pixels into a set of one or more pixel groups, wherein the means for combining comprises means for combining candidate pixels into the same group if the candidate pixels are adjacent to one another;
means for classifying each pixel group in the set of one or more pixel groups as being part of an eye or not part of an eye;
means for checking whether a flash was used in capturing the image, wherein the means for checking whether a flash was used in capturing the image comprises means for checking whether a flash used flag is set in a header corresponding to the image; and

Abstract
Red-eye detection based on red region detection with eye confirmation initially identifies pixels that correspond to the color of red-eye within an image. A determination is then made as to whether these identified pixels and surrounding areas are part of an eye or not part of an eye. Those identified pixels that are determined to be part of an eye are the detected red-eye regions.
