    • A method of detecting and correcting an eye defect within an acquired digital image comprising a multiplicity of pixels indicative of color and forming various shapes within the image is disclosed. A probable size distribution of eye regions, if any, in the image is determined using image meta-data and human anthropometric data, the meta-data including information describing conditions under which the image was acquired. A candidate eye region in the image is detected and whether it falls within the size distribution is determined. In respect of a candidate eye region falling within the size distribution, the anthropometric data is used to search for the presence of at least one of a second eye, lips, nostrils and surrounding face. If the search is successful, a probability that the candidate eye defect region is an actual eye region is increased. The candidate eye region is confirmed as an actual eye region if the probability is above a certain threshold. If the confirmed eye region has a color representative of a red-eye defect, the red-eye defect is corrected.
    • 检测和校正获取的数字图像之内的一种眼缺陷包括指示颜色的像素的多个,并形成图像内的各种形状的方法是游离缺失盘。 眼睛区域的可能尺寸分布,如果有的话,在图像中是确定性的使用图像的元数据和人类人体测量数据开采,所述元数据信息包括描述的条件下哪些其中所获取的图像。 当检测到图像中的候选眼部区域和无论尺寸分布内必要是确定性的开采它。 在关于一个候选眼部区域落入尺寸分布内的,人体测量数据被用来搜索第二眼睛,嘴唇,鼻孔中的至少一个和围绕面部的存在。 如果搜索成功,概率确实候选眼部缺陷区域是一个实际的眼部区域增大。 候选眼部区域被确认为实际眼睛区域,如果概率高于某些阈值。 如果确认的眼睛区域具有代表性的红眼缺陷的颜色,红眼缺陷进行校正。
