Many categories of objects, such as human faces, can be naturally viewe d as a composition of several different layers. For example, a bearded face with glasses can be decomposed in three layers: a layer for glasses, a layer for the beard and a layer for other permanent facial features. While m odeling such a face with a linear subspace model could be very difficult, layer separation allows for easymodeling and modification of some certain structures while leaving others unchanged. In this paper, we present a method for automatic layer extraction and its applications to face synthesis and editing. Layers are automatically extracted by utilizing the differences between subspaces and modeled separately. We show that our method can be us ed for tasks such beard removal (virtual shaving), beard synthesis, and beard transfer, among others.
