The program searches for all the faces in the image. This unique technology
saves users the hassle of having to manually select individual faces.
The software then scans all the eyes before narrowing down the red-eyes.
Utilizing this intelligent search method, the program can remove all
of the red-eyes in a group picture.

The red-eyes are detected using color, intensity and
size information. Further tests on color variation, redness, and
redness variation are performed to determine the different degrees
of redness surrounding the red-eye area.
