Method and apparatus for red-eye detection in an acquired digital image based on image quality pre and post filtering
First Claim
1. A method for red-eye detection and image correction in an acquired digital image comprising:
- a) acquiring a first image;
b) analyzing the first acquired image to provide one or more characteristics indicative of image quality;
c) determining if one or more corrective processes can be beneficially applied to said first acquired image according to said characteristics;
d) establishing an order for applying one or more of such corrective processes and detecting red-eye defects, and f) applying said one or more of such corrective processes to said first acquired image and detecting red-eye defects according to said established order.

Abstract
A method for red-eye detection in an acquired digital image comprises acquiring a first image and analyzing the first acquired image to provide characteristics indicative of image quality. The process then determines if one or more corrective processes can be beneficially applied to the first acquired image according to the characteristics. Any such corrective processes are applied and red-eye defects are detected in an established order established according to determination and analysis of characteristics of the corrective process and/or resulting image qualities. Defect correction can comprise applying one or more image correction operations, or a chain of two or more red-eye filters to the first acquired image. In this case, prior to the detecting step, it is determined if the red-eye filter or red eye filter chain should be applied before or after image corrective processes and whether the red eye filter can be adapted in accordance with the characteristics. The red-eye filter and the order in which it is executed in relation to the various image corrective operations may be adapted accordingly.
