Abstract
A novel method for representing 3-D objects that unifies viewer
and model centered object representations is presented. A unified 3-D
frequency-domain representation (called volumetric/iconic spectral
signatures-V/ISS) 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 V/ISS representation call be
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 are also presented
