Abstract:
A digital image processing method for identifying potential red-eye regions of a digital image, said method comprising:receiving a digital image defined by a plurality of pixels; locating regions of interest within said digital image that include pixels that represent a specular reflection; and, identifying each region of interest as a potential red-eye region; wherein said step of locating regions of interest in said digital image comprises: examining luminance-chrominance data for each pixel of said digital image; identifying a group of adjacent pixels of said digital image as a potential specular reflection if said group of adjacent pixels comprises pixels having luminance-chrominance characteristics of a specular reflection; for each identified potential specular reflection, determining at least one geometric attribute of said potential specular reflection; comparing the at least one geometric attribute of said potential specular reflection to a desired geometric attribute; and, identifying said potential specular reflection as a specular reflection if said at least one geometric attribute conforms to said desired geometric attribute.
