  • Cavalieri integration 
    Ackermann, Etienne Rudolph; Grobler, Trienko Lups; Kleynhans, Waldo; Olivier, Jan Corne; Salmon, Brian Paxton; Van Zyl, A.J. (Taylor & Francis, 2012-04)
    We use Cavalieri’s principle to develop a novel integration technique which we call Cavalieri integration. Cavalieri integrals differ from Riemann integrals in that non-rectangular integration strips are used. In this ...
  • Detecting land cover change using an extended Kalman filter on MODIS NDVI time-series data 
    Kleynhans, Waldo; Olivier, Jan Corne; Wessels, K.J. (Konrad); Salmon, Brian Paxton; Van den Bergh, Frans; Steenkamp, Karen C. (Institute of Electrical and Electronics Engineers, 2011-05)
    A method for detecting land cover change using NDVI time series data derived from 500m MODIS satellite data is proposed. The algorithm acts as a per pixel change alarm and takes as input the NDVI time series of a 3x3 ...
  • Improving land cover class separation using an extended Kalman filter on MODIS NDVI time-series data 
    Kleynhans, Waldo; Olivier, Jan Corne; Wessels, K.J. (Konrad); Van den Bergh, Frans; Salmon, Brian Paxton; Steenkamp, Karen C. (Institute of Electrical and Electronics Engineers, 2009)
    It is proposed that the normalized difference vegetation index time series derived from Moderate Resolution Imaging Spectroradiometer satellite data can be modeled as a triply (mean, phase, and amplitude) modulated cosine ...
  • 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 ...
  • Manifold adaptation for constant false alarm rate ship detection in South African oceans 
    Schwegmann, Colin Peter; Kleynhans, Waldo; Salmon, Brian Paxton (Institute of Electrical and Electronics Engineers, 2015-07)
    The detection of ships at sea is a difficult task made more so by uncooperative ships, especially when using transponder based ship detection systems. Synthetic Aperture Radar imagery provides a means of observation ...
  • 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 ...
  • Multiview deep learning for land-use classification 
    Luus, Francois Pierre Sarel; Salmon, Brian Paxton; Van den Bergh, Frans; Maharaj, Bodhaswar Tikanath Jugpershad (Institute of Electrical and Electronics Engineers, 2015-12)
    A multiscale input strategy for multiview deep learning is proposed for supervised multispectral land-use classification and it is validated on a well-known dataset. The hypothesis that simultaneous multiscale views can ...
  • Rapid detection of new and expanding human settlements in the Limpopo province of South Africa using a spatio-temporal change detection method 
    Kleynhans, Waldo; Salmon, Brian Paxton; Wessels, K.J. (Konrad); Olivier, Jan Corne (Elsevier, 2015-08)
    Recent development has identified the benefits of using hyper-temporal satellite time series data for land cover change detection and classification in South Africa. In particular, the monitoring of human settlement expansion ...
  • Unsupervised land cover change detection : meaningful sequential time series analysis 
    Salmon, Brian Paxton; Olivier, Jan Corne; Wessels, K.J. (Konrad); Kleynhans, Waldo; Van den Bergh, Frans; Steenkamp, Karen C. (Institute of Electrical and Electronics Engineers, 2011-06)
    An automated land cover change detection method is proposed that uses coarse spatial resolution hyper-temporal earth observation satellite time series data. The study compared three different unsupervised clustering ...
  • The use of a multilayer perceptron for detecting new human settlements from a time series of MODIS images 
    Salmon, Brian Paxton; Olivier, Jan Corne; Kleynhans, Waldo; Wessels, K.J. (Konrad); Van den Bergh, Frans; Steenkamp, Karen C. (Elsevier, 2011-12)
    This paper presents a novel land cover change detection method that employs a sliding window over hyper-temporal multi-spectral images acquired from the 7 bands of the MODerate-resolution Imaging Spectroradiometer (MODIS) ...
  • 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 ...
