Multitask learning and data distribution search in visual relationship recognition
(Stellenbosch : Stellenbosch University., 2020-03)ENGLISH ABSTRACT: An image can be described by the objects within it, as well as the interactions between those objects. A pair of object labels together with an interaction label can be assembled into what is known as ... -
Image and attribute based identification of Protea species
(Stellenbosch : Stellenbosch University., 2020-04)ENGLISH ABSTRACT: The flowering plant genus Protea is a dominant representative for the biodiversity of the Cape Floristic Region in South Africa, and from a conservation point of view important to monitor. The recent surge ... -
Automatic video captioning using spatiotemporal convolutions on temporally sampled frames
(Stellenbosch : Stellenbosch University., 2020-03)ENGLISH ABSTRACT: Being able to concisely describe content in a video has tremendous potential to enable better categorisation, indexed based-search and fast content-based retrieval from large video databases. Automatic ... -
Evaluating the effectiveness of neural network techniques in the forecasting of South African basic fuel prices
(Stellenbosch : Stellenbosch University, 2019-04)ENGLISH ABSTRACT : South Africa has a number of fuel grades available to consumers, one of the most popular being the 95 unleaded standard. The price of this fuel is comprised of many components including transport fees, ... -
Data-driven river flow routing using deep learning: predicting flow along the lower Orange river, Southern Africa
(Stellenbosch : Stellenbosch University, 2019-04)ENGLISH ABSTRACT : The Vanderkloof Dam, located on the Orange River, is responsible for the water supply to consumers along its 1 400 km reach up to where it flows into the Atlantic Ocean. The Vaal River, which joins the ... -
Ear-based biometric authentication
(Stellenbosch : Stellenbosch University, 2019-04)ENGLISH ABSTRACT : In this thesis novel semi-automated and fully automated ear-based biometric authentication systems are proposed. Within the context of the semiautomated system, a region of interest (ROI) that contains ... -
Transcriptomic profile based cancer disease prediction and patient survival time differentiation
(Stellenbosch : Stellenbosch University, 2018-12)ENGLISH ABSTRACT : Cancer disease is an abnormal growth of cells, which may be caused by mutations in genes which, as a result, alter the way cells function mainly in the way they grow and divide. Cancer cells are regulated ... -
Systems level cancer disease target identification using tumor microenvironment dynamics
(Stellenbosch : Stellenbosch University, 2018-12)ENGLISH ABSTRACT : Cancer is the second driving reasons for death around the world. It is an abnormal growth of cells which can migrate and recreate cellular microenvironment and can also be caused by successive alterations ... -
Application of convolutional neural networks to building segmentation in aerial images
(Stellenbosch : Stellenbosch University, 2018-12)ENGLISH ABSTRACT : Aerial image labelling has found relevance in diverse areas including urban management, agriculture, climate, mining, and cartography. As a result, research efforts have been intensified to find fast ... -
Incompressible flow with variations in density
(Stellenbosch : Stellenbosch University, 2018-12)ENGLISH ABSTRACT : This study involves the investigation of incompressible flow with variable density. The fact that variable density does not necessarily imply that the flow is compressible, may require some clarification. ... -
Comparison of methods for solving Sylvester systems
(Stellenbosch : Stellenbosch University, 2018-12)ENGLISH ABSTRACT :This thesis serves as a comparative study of numerical methods for solving Sylvester equations, which are linear matrix equations of the form AX + XB + C = 0. These equations have important applications ... -
Hand vein-based biometric authentication with limited training samples
(Stellenbosch : Stellenbosch University, 2018-03)ENGLISH ABSTRACT : A number of novel hand vein-based biometric authentication systems are proposed. Said systems are non-intrusive and may for example assist with user authentication at automated teller machines. An ... -
Short-term stream flow forecasting and downstream gap infilling using machine learning techniques
(Stellenbosch : Stellenbosch University, 2018-03)ENGLISH ABSTRACT : Stream flow is an important component in the hydrological cycle and plays a vital role in many hydrological applications. Accurate stream flow forecasts may be used for the study of various hydro-environmental ... -
Automated elephant detection and classification from aerial infrared and colour images using deep learning
(Stellenbosch : Stellenbosch University, 2018-03)ENGLISH ABSTRACT : In this study we attempt to detect and classify elephants in aerial images using deep learning. This is not a trivial task even for a human since elephants naturally blend in with their surroundings, making ... -
Developing a methodology for the assessment of wave energy along the South African Coast
(Stellenbosch : Stellenbosch University, 2018-03-19)ENGLISH ABSTRACT : Ocean wave energy can become one of the alternative energy resources for fossil-fuelled power generation in South Africa. Due to global warming, several studies about the generation of wave energy have ... -
Modifying and generalising the Radon transform for improved curve-sensitive feature extraction
(Stellenbosch : Stellenbosch University, 2017-12-01)ENGLISH ABSTRACT : In this thesis a novel and generic feature extraction protocol that is based on the well-known standard discrete Radon transform (SDRT) is presented. The SDRT is traditionally associated with computerised ... -
Predicting the effect of biofilm growth on the pressure drop over a biofilter
(Stellenbosch : Stellenbosch University, 2017-12)ENGLISH ABSTRACT : Hydrogen sulphide is a poisonous gas produced by several industries. It is therefore crucial to investigate and mathematically model the environmentally friendly biofiltration process, which has the ... -
Text detection in natural images using convolutional neural networks
(Stellenbosch : Stellenbosch University, 2017-03)ENGLISH ABSTRACT : In this study we attempt to solve the problem of text detection in natural images. This requires us to identify regions in a natural image that contain text. Possible applications range from assistive ...
