Research in Model-Based Change Detection and Site Model Updating

摘要

The major goal of the RADIUS project is to provide tools to assist an image analyst in the analysis of large amounts of imagery. The site models, an essential component of the analysis process, are useful in a variety of ways: projecting the expected structures from the current view point, assisting with the task of change detection, and cueing an analyst to the appropriate parts of an image. Our major RADIUS project deals with change detection and site model updating with particular focus on stationary structures. Some of these techniques also are applicable to automatic site modeling and some of our change detection techniques may apply to detection of larger mobile objects, such as airplanes. We have implemented an interactive modeling system that works in conjunction with our automatic system to minimize the need for tedious interaction.
