Line Detection in Satellite Imagery

Automated Detection of Clouds in Satellite Imagery

Global-scale Object Detection Using Satellite Imagery

In recent years, there has been a substantial increase in the availability of high-resolution commercial satellite imagery, enabling a variety of new remote-sensing applications. One of the main challenges for these applications is the accurate and efficient extraction of semantic information from satellite imagery. In this work, we investigate an important instance of this class of challenges ...

Higher Order Active Contours and their Application to the Detection of Line Networks in Satellite Imagery

We present a novel method for the incorporation of shape information into active contour models, and apply it to the extraction of line networks (e.g. road, water) from satellite imagery. The method is based on a new class of contour energies. These energies are quadratic on the space of one-chains in the image, as opposed to classical energies, which are linear. They can be expressed as double...

Automatic Detection of Changes in Road Databases Using Satellite Imagery

An automatic procedure is developed for detection of changes between an existing road database and a newly registered satellite image, rectified to an orthophoto. The approach uses the existing database to force the detection and delineation of the corresponding road network in the image. Each road segment is handled separately during the comparison between the image and the database as the pos...

Tsunami Damage Detection Using Moderate-resolution Satellite Imagery

A moment-magnitude 9.0 earthquake struck the area off the western coast of northern Sumatra on 26 December 2004, which triggered massive tsunamis inundating the coastal areas in the countries along the Indian Ocean Rim. Various moderateto high-resolution satellite images were obtained before and after the tsunami attack and used for emergency management. High-resolution satellite (e.g. IKONOS) ...
