Low-Level Feature Extraction:

Useful to extract cues from non-panchromatic images such as SAR, IFSAR, HYDICE, DEMs, LIDAR and HalfTones. References:

Airport Runway Detection:

Examples:
- Boston LOGAN: image and runways... an example of fully automated detection.
- New York JFK: Markings detected to verify runway hypotheses. Note that center "runway" is not a runway now, thus not reported as such.

Harbor Pier Detection:

Example:
- Navy facility, San Diego: Image, water boundary, seeds, pier seeds, pier groups, piers

Evidence of Construction:

Example:
- Los Angeles area: Image & detected site, proximity groups... an example of automated detection.

Building Detection:

Example:
- 20-sec video of automated and post-assisted detection (10 mouse clicks required).

- Stereo: Mohan, Chung, Nevatia. PAMI,CVPR
- Multiview: Noronha, Kim, Huertas, Nevatia. CVPR, IUW
- Multisensor: Huertas, Kim, Nevatia. IUW

Change Detection:

Example:
- 15-sec video of model validation and change detection and reporting.

- Huertas, Nevatia. ASCONA95, ICCV98

Aircraft Detection:

Examples:
- C-130 Hercules: Edges, model and match
- C-130 Hercules: Image, edges, model, model match and edge match
- C-130 Hercules: Image, edges, model, model match and edge match
- DeHavilland: Image, edges, model, model match and edge match
- Missing aircraft: Edges, poor match
