Physics-based modeling and analysis of cloth draping: estimating cloth
draping parameters from range data of real cloth drapes. The University
of Illinois at Urbana-Champaign is seeking qualified commercial entities
to develop this technology under license. See the short tech.
3-D reconstruction of human bodies by integration of occluding contours
Dressing humans into virtual garment
Modeling dressed humans from images
Virtual reality (CAVE and Immersa Desk)
Filtering and automatic acqusition of Scanning Electron Microsocope images
Articulation models of humans and real-time tracking with applications
to human-computer interaction
Transformation invariant methods in computer vision: transformed mixtures
of Gaussians (TMG), transformed component analysis (TCA) and their applications
to digit recognition, face and expression recognition, extraction of key
objects in videos, tracking and other areas of image/video understanding.
Participated in the Garment
Project, whose purpose was development of a 3D CAD System for the Garment
Industry. In particular, developed an algorithm for 3-D reconstruction
of human bodies from images using occluding contours and structured light
This program is a part of collaboration between UIC and the University
of Belgrade, and is meant to introduce several best Belgrade students to
the graduate studies in USA. During the program, I worked on a project
related to image restoration using projections onto convex sets.

Part of the research and development engineering team, participated in
the design of telephone traffic monitoring system. In particular, developed
the database of traffic activity and a user-friendly Visual-Basic program
for database retrieval and traffic statistics computation.
