Detecting Changes in Aerial Views of Man-Made Structures
- …Many applications require detecting structural changes in a scene over a period of time. Comparing intensity values of successive images is not effective as such changes don't necessarily reflect actual changes at a site but might be caused by changes in the view point, illumination and seasons. We …

Multisensor Integration for Building Modeling
- …Machine perception can benefit from the use of features extracted from data provided by a variety of sensor modalities. Recent advances in sensor design makes it possible to incorporate multiple sensors into vision systems for increased capability. Two important issues must be considered for the int…

Evaluation of stereo vision obstacle detection algorithms for off-road autonomous navigation
- …Reliable detection of non-traversable hazards is a key requirement for off-road autonomous navigation. Under the Army Research Laboratory (ARL) Collaborative Technology Alliances (CTA) program, JPL has evaluated the performance of seven obstacle detection algorithms on a General Dynamics Robotic Sys…

Using Generic Knowledge in Analysis of Aerial Scenes: A Case Study
- …Our goal is to produce high-quality symbolic descriptions from aerial scenes. We have chosen to work in the domain of large commercial airport complexes. Such scenes have a variety of features such as the transportation network, building structures, and mobile objects. This paper concentrates on det…

Automatic Description of Complex Buildings with Multiple Images
- …Three-D building detection and description is a practical application of 3-D object description, a key task of computer vision. We present an approach to detecting and describing buildings of polygonal rooftops by using multiple, overlapping images of the scene. First, 3-D features are generated by …

Automatic Description of Gable Buildings of Polygonal Boundaries
- …We present a model-based approach to detecting and describing composition of buildings with flat or gabled polygonal rooftops. Previous approaches have dealt with either simpler models or models which lack geometric information. In spite of increasing model complexity, we maintain the computation af…
