Abstract:
1. A method for detecting a redeye defect in a digital image containing an eye, the method comprising the following steps: (a) converting the digital image into an intensity image, including: (b) segmenting at least a portion of the intensity image into segments each having a local intensity maximum, (c) thresholding a corresponding portion of the digital image to identify regions exhibiting an intensity measure that is above a threshold value, (d) selecting a region from at least two regions of step (c) having the most extreme average intensity, and (e) identifying segments from step (b) intersecting the region selected at step (d) according to a pre-determined criterion, wherein the average intensities of the two regions from step (c) having the highest and next highest average intensities differ by more than a predetermined amount, and the region selected at step (d) is the region having the highest average intensity.
