Finding similar faces

In this paper, we propose a method to match similar faces despite photos, which are taken from different sources on Internet, could have different scenes, illumination and posing. Interest points are used to recognize faces, and some points are eliminated in order to find best matching points which pair the similar face. Difference between two matching points is used to define similarity of the faces. Inspite of physical changes due to old age, plastic surgery, make-up or clothing, experiments show that given face image can be successfully matched with a similar face within a database composed of celebrity photos.
