Abstract:

The model based detection schemes presented in this report incorporate Image Understanding IU techniques that can be directed by the image analyst to conduct spatially constrained analyses, whose outcomes may be indicative of occurrences of change with special intelligence significance. The aerial image exploitation system is site model driven, and is generally based on three classes of primitives object primitives, spatial primitives, temporal primitives. This work emphasizes the use of geometric i.e., object and spatial primitives. These take the form of site models implemented in the RADIUS Common Development Environment RCDE. The models encode the spatial relationships between fixed objects of interest in a site, such as buildings, roads, etc.
