Facial Feature Reconstruction using Structure from Motion
(Stellenbosch : University of Stellenbosch, 2005-03)
Structure from Motion suggests that an object or scene’s three-dimensional
structure can be determined from its observed two-dimensional motion. Human
efforts, manifested in computer algorithms, try to mimic the ...
Face recognition using Hidden Markov Models
(Stellenbosch : University of Stellenbosch, 2005-03)
This thesis relates to the design, implementation and evaluation of statistical
face recognition techniques. In particular, the use of Hidden Markov
Models in various forms is investigated as a recognition tool and ...
Low impedance characterisation and modeling of high power LDMOS devices
(Stellenbosch : University of Stellenbosch, 2005-12)
In RF power transistor characterisation, the designer is confronted with low impedance
measurements (typically from 1 Ohm to 12 Ohm). These transistors are contained in
metal-ceramic packages of which the lead widths ...
Estimation of Synchronous Generator Parameters using Time-domain Responses
(Stellenbosch : University of Stellenbosch, 2005-12)
Power system stability simulations are of growing importance for studying the operational
integrity of modern power systems, especially in developing economies where generating and
transmission capacity lead the demand ...
Orthogonal frequency division multiplexing (OFDM) implementation as part of a software devined radio (SDR) environment
(Stellenbosch : University of Stellenbosch, 2005-12)
Orthogonal Frequency Division Multiplexing (ODFM) has gained considerable attention the past couple of years. In our modern world the need for faster data transmission is never-ending. OFDM modulation provides us with a ...
Improving Automatic Position Reporting System (APRS) throughput and reliability
(Stellenbosch : University of Stellenbosch, 2005-03)
The Automatic Position Reporting System (APRS) is a well-established packet communication
protocol that offers users a graphical position display system and a peer-to-peer
textual message service. APRS is used in temporary ...
Onboard image geo-referencing for LEO satellites
(Stellenbosch : University of Stellenbosch, 2005-12)
The next generation of small satellites will require significant onboard data processing
and information extraction capabilities to keep up with industry demands. The need for
value added information products is ...
Investigating cost-effective EMC methods
(Stellenbosch : University of Stellenbosch, 2005-12)
Due to the expensive nature of high frequency measurements in the EMC (Electromagnetic
Compatability) field, more affordable methods of measurement instrumentation and
environments are investigated. Different calibration ...
Neutral-point-clamped shunt active filter
(Stellenbosch : University of Stellenbosch, 2005-03)
This thesis presents the design and implementation of a Neutral-Point-Clamped
(NPC) shunt Active Filter (AF) for non-linear loads. A NPC shunt AF is an attractive
solution for AFs at the medium volage level, because it ...
3D tracking between satellites using monocular computer vision
(Stellenbosch : University of Stellenbosch, 2005-03)
Visually estimating three-dimensional position, orientation and motion, between an observer
and a target, is an important problem in computer vision. Solutions which compute threedimensional
movement from two-dimensional ...
