Automatic real-time facial expression recognition for signed language translation
(University of the Western Cape, 2006)We investigated two computer vision techniques designed to increase both the recognition accuracy and computational efficiency of automatic facial expression recognition. In particular, we compared a local segmentation of ... -
Cephalometric landmark detection: Artificial intelligence vs human examination
(University of Western Cape, 2021)Cephalometric landmark detection is important for accurate diagnosis and treatment planning. The most common cause of random errors, in both computer-aided cephalometry and manual cephalometric analysis, is inconsistency ... -
Computational prediction of host-pathogen protein-protein interactions
(University of the Western Cape, 2017)Supervised machine learning approaches have been applied successfully to the prediction of protein-protein interactions (PPIs) within a single organism, i.e., intra-species predictions. However, because of the absence of ... -
Computational strategies to identify, prioritize and design potential antimalarial agents from natural products
(University of the Western Cape, 2015)Introduction: There is an exigent need to develop novel antimalarial drugs in view of the mounting disease burden and emergent resistance to the presently used drugs against the malarial parasites. A large amount of natural ... -
Concept Based Knowledge Discovery from Biomedical Literature
(University of the Western Cape, 2009)This thesis describes and introduces novel methods for knowledge discovery and presents a software system that is able to extract information from biomedical literature, review interesting connections between various ... -
Concept Based Knowledge Discovery From Biomedical Literature
(University of the Western Cape, 2009)Advancement in biomedical research and continuous growth of scientific literature available in electronic form, calls for innovative methods and tools for information management, knowledge discovery, and data integration. ... -
A deep learning approach to predicting potential virus species crossover using convolutional neural networks and viral protein sequence patterns
(University of the Western Cape, 2022)Medical science has made substantial progress toward diagnosing, understanding the pathogenesis, and treating various causative agents of infectious disease; however, novel microbial pathogens continue to emerge, and ... -
Designing industrial image processing applications for warehouse management in South Africa
(University of Western Cape, 2021)With conclusive evidence from multiple research studies it is evident that the lack of real time information flows in Warehouse Management (WM) operations leads to rigid, un-optimised supply chains. Industrial Image ... -
Development of a simple artificial intelligence method to accurately subtype breast cancers based on gene expression barcodes
(University of the Western Cape, 2018)INTRODUCTION: Breast cancer is a highly heterogeneous disease. The complexity of achieving an accurate diagnosis and an effective treatment regimen lies within this heterogeneity. Subtypes of the disease are not simply ... -
End-to-end single-rate multicast congestion detection using support vector machines
(2008)IP multicast is an efficient mechanism for simultaneously transmitting bulk data to multiple receivers. Many applications can benefit from multicast, such as audio and videoconferencing, multi-player games, multimedia ... -
Geo-physical parameter forecasting on imagery{based data sets using machine learning techniques
(University of Western Cape, 2021)This research objectively investigates the e ectiveness of machine learning (ML) tools towards predicting several geo-physical parameters. This is based on a large number of studies that have reported high levels of ... -
Handwritten alphabet character recognition using audio signatures and machine learning
(University of the Western Cape, 2023)This research investigates the creation of an audio-based character recognition system that is able to segment, process and recognise uppercase English letters continuously drawn by the user on a given writing surface ... -
miRNAMatcher: High throughput miRNA discovery using regular expressions obtained via a genetic algorithm
(University of the Western Cape, 2008)In summary there currently exist techniques to discover miRNA however both require many calculations to be performed during the identification limiting their use at a genomic level. Machine learning techniques are currently ... -
On the efficacy of enhanced feature selection methods for supervised crime prediction
(University of the Western Cape, 2023)The challenge of crime across the globe has necessitated several considerations for crime preventive measures. There exist a variety of crime prevention strategies, such as the use of necessary weapons or tools to respond ... -
Prediction of antimicrobial peptides using hyperparameter optimized support vector machines
(University of the Western Cape, 2011)Antimicrobial peptides (AMPs) play a key role in the innate immune response. They can be ubiquitously found in a wide range of eukaryotes including mammals, amphibians, insects, plants, and protozoa. In lower organisms, ... -
Robust recognition of facial expressions on noise degraded facial images
(University of the Western Cape, 2011)We investigate the use of noise degraded facial images in the application of facial expression recognition. In particular, we trained Gabor+SVMclassifiers to recognize facial expressions images with various types of noise. ... -
