We describe a method for detecting rectilinear buildings and constructing their 3-D shape
descriptions from a single aerial image of a general viewpoint. 2-D roof hypotheses are …

In this thesis, we present a fast approach to automated generation of textured 3D city models
with both high details at ground level and complete coverage for bird's-eye view. A ground …

Abstract In this Automatic Population of Geospatial Databases (APGD) overview paper, we
describe our progress in developing and evaluating a generic context-based architecture …

To date, computer vision methods have largely focused on extraction from panchromatic
imagery. Despite significant technological advances, road extraction algorithms have fallen …

A multi-image focus of attention mechanism has been developed that can quickly distinguish
raised objects like buildings from structured background clutter typical to many aerial image …

The increasing number of high resolution image sensors in a near future, as well as the
need for realistic 3D site databases for applications like simulation, terrestrial mission …

Abstract The RADIUS Common Development Environment (RCDE) pulls together many
diverse functions into an integrated whole. The main goal of the environment is to provide a …

This paper describes FREEDIUS, an open-source image understanding system. FREEDIUS
is a Lisp-C hybrid system that exploits CLOS for rapid prototyping, flexibility of presentation …

This paper presents a method for on-the fly snakes construction from video input. The
algorithm is intended to be used as a site model construction tool dedicated to ribbon-like …

We describe a system for converting RADIUS site models into a Web-accessible form. Once
converted, the site models can be downloaded and viewed with standard, off-the-shelf Web …
