Red eye detection and correction |
摘要 |
A system suited to correction of red eyes in images includes a detection module which, for a plurality of pixels in a digital image, assigns a probability that a pixel is within a red eye. The probability has a value which may vary from a minimum value to maximum value. A classifier module classifies a patch of the image comprising a region of contiguous pixels which have at least a threshold probability that the pixel is within a red eye. The classifier module distinguishing patches which have a likelihood of including a red eye from other patches which have a likelihood of containing a face or background error rather than a redeye. A correction module assigns a correction to apply to pixels which are in a region of contiguous pixels having at least the threshold probability that the pixel is within a red eye and for which the associated patch has been identified by the classifier as having a probability of including a red eye.
