ABSTRACT:
Redeye removal methods detect redeyes in a two-step procedure. In the first step it detects faces in the input image and in the second step it searches for redeyes in the detected faces. The methods include the introduction of an efficient skin tone detector that reduces the average complexity of a Viola-Jones based face. We also introduce a summed area table (SAT) based optimization in our eye detector stage that reduces the complexity in the eye detector by a factor of 5× when compared to an optimized direct search method.
