Blind assessment of image blur using the Haar wavelet

Author: Bachoo, A Date: Oct 2010 Images and video captured in real world situations generally have distorted digital pixel values. A variety of situations can cause these image degradations: sensor motion, environmental conditions and random noise. A crucial procedure in ... Read more
Comparison of data file and storage configurations for efficient temporal access of satellite image data

Author: Bachoo, A ; Van den Bergh, F ; Gazendam, A Date: 2009 Satellite data volumes have seen a steady increase in recent years due to improvements in sensor technology and increases in data acquisition frequency. The gridded MODIS data products, spanning a region of interest of approximately 10° by ... Read more
Comparison of features response in texture-based iris segmentation

Author: Bachoo, A ; Tapamo, J-R Date: Mar 2009 Identification of individuals using iris recognition is an emerging technology. Segmentation of the iris texture from an acquired digital image of the eye is not always accurate - the image contains noise elements such as skin, reflection and ... Read more
Efficient temporal access of satellite image data

Author: Bachoo, A ; Van Den Bergh, F ; Gazendam, AD Date: Nov 2008 A single tile from the gridded MODIS products, spanning a region of interest of approximately 10° by 10°, is stored as an image containing close to six million pixels, with data in multiple spectral bands for each pixel. Time series analyses ... Read more
Influence of using date-specific values when extracting phenological metrics from 8-day composite NDVI data

Author: Bachoo, A ; Archibald, S Date: Jul 2007 Information of vegetation dynamics derived from remotely sensed data is essential for regional natural resource management. A common approach involves using an n-day composite time-series of normalized difference vegetation index (NDVI) ... Read more
Remotely sensed phenology for mapping biomes and vegetation functional types

Author: Wessels, Konrad J ; Steenkamp, Karen C ; Von Maltitz, Graham P ; Archibald, S ; Scholes, RJ ; Miteff, S ; Bachoo, A Date: Jul 2009 This study used remotely-sensed phenology data derived from Advanced Very High Resolution Radiometer (AVHRR), in a fully supervised decision-tree classification based on the new biome map of South Africa. The objectives were: (i) to investigate ... Read more
