AFFILIATION:University of Ljubljana, Slovenia, http://lrv.fri.uni-lj.si/

PLACE: CSE Seminar Room, Level 1, K17

ABSTRACT:

A representation of objects by their constituent parts is an important
paradigm for representing complex 3D objects in computer vision.
Superquadrics, a family of parametric models that cover o continuum
of smooth 3D shapes, are among the most popular part models which
can be controlled by a small number of parameters and augmented with
global or local deformations.

The presentation will provide the audience with an overview of geometric
properties of superquadrics and will outline how superquadrics can
be used for interleaved segmentation and shape recovery of range images.
Several applications of superquadrics will be mentioned, ranging from
robotics to medicine. The speaker will focus on range image registration
and on object recognition of flexible complex objects such as the
human body.

BIOGRAPHY OF SPEAKER:

Franc Solina (franc.solina@fri.uni-lj.si) is a Professor at the Faculty
of Computer and Information Science of the University of Ljubljana in
Slovenia. He received the Dipl. Ing. (1979) and M.S. (1982) degrees
in Electrical Engineering from the University of Ljubljana, and
the Ph.D. degree in Computer Science from the University of Pennsylvania
in 1987. Prof. Solina founded the Computer Vision Laboratory at
University of Ljubljana in 1991. His research is devoted to several
aspects of computer vision, in particular, using 3D superquadric
models for segmentation and object recognition. Other areas that
interest Prof. Solina include the use of computer vision methods
in relation to multimedia and in the context of new media art.
