US08811683B2	Automatic red-eye repair using multiple recognition channels This disclosure pertains to apparatuses, methods, and computer readable media for automatic red-eye repair using multiple recognition channels. While it is possible to manually specify all of the eyes in an image to be repaired, it is desirable for repair to happen automatically.
