Abstract:
1. A method of detecting and correcting an eye defect within an acquired digital image comprising a multiplicity of pixels indicative of luminance and color, the pixels forming various shapes within the image, the method comprising: acquiring a digital image including said multiplicity of pixels indicative of luminance and color; detecting a candidate eye defect region based on degree of color or shape, or both, within the digital image; determining a size of the candidate eye defect region; analyzing meta-data information including image acquisition device-specific information, including distance information as recorded by an auto-focus mechanism of the portable digital camera, and information describing conditions under which the image was acquired; analyzing anthropometric information including statistics relating to relationships between said size of said candidate eye defect region and said distance information as recorded by said auto-focus mechanism and between said size of said candidate eye defect region and a location of a second detected eye, lips, nostrils or a surrounding face, or combinations thereof; and determining, based at least in part on said meta-data and anthropometric information, and on a probability of detection of said second detected eye, lips, nostrils or said surrounding face, or combinations thereof, whether said candidate eye defect region is suspected as including an eye defect region; and filtering said candidate eye defect region from the digital image.
