Author:Holtzhausen, S; Matsebe, O; Tlale, NSDate:2008AUVs are ideal platforms for search and rescue operations. They can also be used for inspection of underwater terrains. These vehicles need to be autonomous and robust to cope with unpredictable current and high pressures. In this paper it ...Read more
Author:Salmon, BP; Kleynhans, W; Van den Bergh, F; Olivier, JC; Wessels, Konrad JDate:Jul 2012In this paper, the internal operations of an Extended Kalman Filter is investigated to see if any useful information can be derived to detect land cover change in a MODIS time series. The Extended Kalman Filter expands its internal covariance ...Read more
Author:Kleynhans, W; Olivier JC; Wessels, Konrad J; Van Den Bergh F; Salmon BP; Steenkamp Karen CDate:15 Dec 2009It is proposed that the NDVI time-series derived from MODIS satellite data can be modelled as a triply (mean, phase and amplitude) modulated cosine function. Secondly, a non-linear Extended Kalman Filter is developed to estimate the parameters ...Read more
Author:Kleynhans, W; Olivier, JC; Salmon, BP; Wessels, Konrad J; Van den Bergh, FDate:Jul 2009It is proposed that the NDVI time series derived from MODIS multitemporal remote sensing data can be modelled as a triply (mean, phase and amplitude) modulated cosine function. A non-linear Extended Kalman Filter was developed to estimate the ...Read more
Author:Matsebe, O; Holtzhausen, S; Kumile, CM; Tlale, NSDate:Dec 2008The “solution” of the Simultaneous Localisation and Mapping (SLAM) problem has been one of the notable successes of the robotics community. SLAM has been formulated and solved as a theoretical problem in a number of different forms. SLAM has ...Read more
Author:Van Den Bergh, F; Udahemuka, G; Van Wyk, BJDate:Jul 2009A 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
