Comparison of canny and V1 neural network based edge detectors applied to road extraction

Author: Hauptfleisch, AC ; Van Den Bergh, F ; Bachoo, AK ; Engelbrecht, AP Date: Nov 2006 The Anti-parallel edge Centerline Extractor (ACE) algorithm is designed to extract road networks from high resolution satellite images. The primary mechanism used by the algorithm to detect the presence of roads is a filter that detects ... Read more
HiTempo: a platform for time-series analysis of remote-sensing satellite data in a high-performance computing environment

Author: Van den Bergh, F ; Wessels, Konrad J ; Miteff, S ; Van Zyl, TL ; Gazendam, AD ; Bachoo, AK Date: Aug 2012 Course resolution earth observation satellites offer large data sets with daily observations at global scales. These data sets represent a rich resource that, because of the high acquisition rate, allows the application of time-series analysis ... Read more
Influence of composite period and date of observation on phenological metrics extracted from MODIS data

Author: Wessels, Konrad J ; Bachoo, AK ; Archibald, S Date: May 2009 Deriving date-specific phenometrics from different multi-day MODIS composite data can potentially yield very different results. The objectives of this study were therefore to quantify the differences between (i) using 8-day vs. 16-day MODIS ... Read more
Land cover change in the Kruger to Canyons Biosphere Reserve (1993-2006): a first step towards a conservation plan for the subregion

Author: Coetzer, KL ; Erasmus, BFN ; Witkowski, ETF ; Bachoo, AK Date: Jul 2010 This paper is a first step towards a conservation plan for the Kruger to Canyons Biosphere Reserve (K2C) on the South African Central Lowveld, quantifying the historical land-cover trends (1993-2006). During the analysis period, 36% of the ... Read more
An Optical tracker for the maritime environment

Author: Bachoo, AK ; Le Roux, F ; Nicolls, F Date: Apr 2011 Optical (visual) tracking is an important research area in computer vision with a wide range of useful and critical applications in defence and industry. The tracking of targets that pose a threat or potential threat to a country's assets and ... Read more
Proven collaboration model for impact generating research with universities

Author: Bezuidenhout, DF ; De Villiers, JP ; Delport, JP ; Bachoo, AK ; Duvenhage, B ; Hattingh, Z ; Calitz, R ; Jeebodh, P Date: 01 Sep 2010 PRISM is one of a family of student sponsorship programmes initiated by the Department of Defence (DoD). The programme facilitates the transfer of knowledge and fosters the development of skilled human capital in the disciplines of optics, ... Read more
Quantitative analysis of the improvement in high zoom maritime tracking due to real-time image enhancement

Author: Bachoo, AK ; De Villiers, JP ; Nicolls, F ; Le Roux, Francois PJ Date: Apr 2011 This work aims to evaluate the improvement in the performance of tracking small maritime targets due to real-time enhancement of the video streams from high zoom cameras on pan-tilt pedestal. Due to atmospheric conditions these images can ... Read more
Quantitative analysis of the improvement in omnidirectional maritime surveillance and tracking due to real-time image enhancement

Author: De Villiers, JP ; Bachoo, AK ; Nicolls, FC ; Le Roux, FPJ Date: Apr 2011 Omnidirectional camera systems are used to supplement RADAR in tracking small craft close in to the ship in a maritime environment. They can simultaneously track multiple targets to provide a more complete situational awareness. Due to their ... Read more
Real-time exposure fusion on a mobile computer

Author: Bachoo, AK Date: Dec 2009 Within the context of video surveillance, object and incident detection by an operator is minimized in over- and under-exposed pixels. Multiple different exposures of the same scene can be fused to create a well-balanced and detailed image ... Read more
A three-step vehicle detection framework for range estimation using a single camera

Author: Kanjee, R ; Bachoo, AK ; Carroll, J Date: Dec 2015 This paper proposes and validates a real-time onroad vehicle detection system, which uses a single camera for the purpose of intelligent driver assistance. A three-step vehicle detection framework is presented to detect and track the target ... Read more
Using the CPU and GPU for real-time video enhancement on a mobile computer

Author: Bachoo, AK Date: Sep 2010 Real-time video enhancement is generally achieved using costly specialized hardware that have specific functions and outputs. Commercial off-the-shelf hardware, such as desktop computers with Graphics Processing Units (GPUs), are also commonly ... Read more
Vision-based adaptive cruise control using pattern matching

Author: Kanjee, R ; Bachoo, AK ; Carroll, J Date: Oct 2013 Adaptive Cruise Control (ACC) is a relatively new system designed to assist automobile drivers in maintaining a safe following distance. This paper proposes and validates a vision-based ACC system which uses a single camera to obtain the ... Read more
