• Image Understanding methods fo Extraction of buildings, roads, and road grids.
• Exploitation of cues from dense DEMs and from multispectral methods.

Preliminary Results

• Sensor Fusion and Information Integration:
  • Experiments with DEM, DTE, DSM (Digital Elevation) (under construction)
  • Experiments with IFSAR (Interferometric SAR) (under construction)
  • Experiments with HYDICE (Hyperspectral)
  • Ft Hood Example: EO only, EO+DEM, EO+HYDICE
  Using HYDICE with EO imagery for Building Modeling
