In this paper we describe a two step algorithm which localizes faces in 2D color images depicting a single face on a complex background. Given a single image, the algorithm roughly determines the skin regions and then searches for eyes within them. A face is localized if at least one eye is present in a skin region. The system is based on a Support Vector Machine trained to separate sub-images representing eyes from others. The algorithm is robust to scale, illumination, pose variations and deals with partial occlusions. Results on several public databases are presented.

Abstract
In this paper we describe a two step algorithm which localizes faces in 2D color images depicting a single face on a complex background. Given a single image, the algorithm roughly determines the skin regions and then searches for eyes within them. A face is localized if at least one eye is present in a skin region. The system is based on a Support Vector Machine trained to separate sub-images representing eyes from others. The algorithm is robust to scale, illumination, pose variations and deals with partial occlusions. Results on several public databases are presented.
