... for the face representation and recognition. Ev- ery face image in the database is represented as a vector of weights, which is the projection of the face image to the ba- sis in the eigenface space. ... a great challenge to face recognition. Two is- sues are central, the first is what features to use to representa face. A face image subjects to changes in viewpoint, illumi- natio...

The performance of face recognition systems has improved significantly since the first au- tomatic face recognition ... dealing with out-of-plane (left-right) rotation. A coarse-to-fine, simple-to- complex architecture, called a detector-pyramid, is designed for the fast detection of multiview f...

... 1. Face position: Face localization is affected by rotation (in-plane and out-of-plane) and distance (scaled faces). 2. Face expression: There are facial expressions that modify the face ... containing all the face sets. L is the set containing all the face- like regions. q F S∈ is a face set; it should contain similar face- like regions in the image. Formally, a face...
