An inductive approach to simulating multispectral MODIS surface reflectance time series

Grobler, Trienko Lups; Ackermann, Etienne Rudolph; Van Zyl, A.J.; Olivier, Jan Corne; Kleynhans, Waldo; Salmon, Brian Paxton (Institute of Electrical and Electronics Engineers, 2013-05)

In this paper, a first order MODIS time series simulator, which uses a Colored Simple Harmonic Oscillator, is proposed. The simulated data can be used to augment data sets so that data intensive classification and change ...
Land cover change detection using autocorrelation analysis on MODIS time-series data : detection of new human settlements in the Gauteng province of South Africa

Kleynhans, Waldo; Salmon, Brian Paxton; Olivier, Jan Corne; Van den Bergh, Frans; Wessels, K.J. (Konrad); Grobler, Trienko Lups; Steenkamp, Karen C. (Institute of Electrical and Electronics Engineers, 2012)

Human settlement expansion is one of the most pervasive forms of land cover change in the Gauteng province of South Africa. A method for detecting new settlement developments in areas that are typically covered by natural ...
Land cover separability analysis of MODIS time series data using a combined simple harmonic oscillator and a mean reverting stochastic process

Grobler, Trienko Lups; Ackermann, Etienne Rudolph; Olivier, Jan Corne; Van Zyl, A.J. (Gusti); Kleynhans, Waldo (Institute of Electrical and Electronics Engineers, 2012-06)

It is proposed that the time series extracted from moderate resolution imaging spectroradiometer satellite data be modeled as a simple harmonic oscillator with additive colored noise. The colored noise is modeled with ...
Meta-optimization of the Extended Kalman filter's parameters through the use of the Bias-Variance Equilibrium Point criterion

Salmon, Brian Paxton; Kleynhans, Waldo; Van den Bergh, Frans; Olivier, Jan Corne; Marais, W.J.; Grobler, Trienko Lups; Wessels, K.J. (Konrad) (IEEE / Institute of Electrical and Electronics Engineers Incorporated, 2014-08)

The extraction of information on land cover classes using unsupervised methods has always been of relevance to the remote sensing community. In this paper, a novel criterion is proposed, which extracts the inherent ...
Using Page's cumulative sum test on MODIS time series to detect land-cover changes

Grobler, Trienko Lups; Ackermann, Etienne Rudolph; Van Zyl, A.J.; Olivier, Jan Corne; Kleynhans, Waldo; Salmon, Brian Paxton (Institute of Electrical and Electronics Engineers, 2013-03)

Human settlement expansion is one of the most pervasive forms of land cover change in South Africa. The use of Page’s Cumulative Sum Test is proposed as a method to detect new settlement developments in areas that were ...
