Note on difference spectra for fast extraction of global image information.

Author: Van Wyk, BJ ; Van Wyk, MA ; Van Den Bergh, F Date: Jun 2007 The concept of an Image Difference Spectrum, a novel tool for the extraction of global image information, is introduced. It is shown that Image Difference Spectra are fast alternatives to granulometric curves, also referred to as pattern ... Read more
Potential fire detection based on Kalman-driven change detection

Author: Van Den Bergh, F ; Udahemuka, G ; Van Wyk, BJ Date: Jul 2009 A new active fire event detection algorithm for data collected with the Spinning Enhanced Visible and Infrared Imager (SEVIRI) sensor, based on the extended Kalman filter, is introduced. Instead of using the observed temperatures of the spatial ... Read more
Preliminary physics-engine model of dolosse interacting with one another

Author: Cooper, Antony K ; Greben, JM ; Van Den Bergh, F ; Gledhill, Irvy MA ; Cannoo, BR ; Steyn, WJVDM ; De Villiers, R Date: Mar 2008 A variety of armour units are used to protect breakwaters, piers and other harbour infrastructure, serving both to absorb the impact of violent seas and to reduce overtopping. A common type of armour unit is the dolos. Coastal engineers use ... Read more
Robust fitting of diurnal brightness temperature cycle

Author: Udahemuka, G ; Van Den Bergh, F ; Van Wyk, BJ ; Van Wyk, MA Date: Nov 2007 Land surface temperatures (LSTs) can be approximated from brightness temperatures observed from satellites. Estimation errors between observed brightness temperatures and a brightness temperature model of a given pixel would provide information ... Read more
