Abstract
A novel method for representing 3D objects that unifies viewer and
model centered object representations is presented. A unified 3D
frequency-domain representation, called volumetric frequency
representation (VFR), encapsulates both the spatial structure of the
object and a continuum of its views in the same data structure. The
frequency-domain image of an object viewed from any direction can be
directly extracted employing an extension of the projection slice
theorem, where each Fourier-transformed view is a planar slice of the
volumetric frequency representation. The VFR is employed for
pose-invariant recognition of complex objects, such as faces. The
recognition and pose estimation is based on an efficient matching
algorithm in a four-dimensional Fourier space. Experimental examples of
pose estimation and recognition of faces in various poses are also
presented
