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 ... -
The application of statistical and machine learning techniques for DDOS detection in network information systems
(University of the Western Cape, 2022)A surge of large-scale Distributed Denial of Service (DDoS) attacks has swept the internet in recent years, possibly presenting a serious threat to industry internet service offerings. These attacks take advantage 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 ... -
A comparative evaluation of population-based optimization algorithms for workflow scheduling in cloud-fog environments
(University of the Western Cape, 2023)Scientific workflows are denoted by interdependent tasks and computations that are aimed at achieving some scientific objectives. The scheduling of these workflows involve the allocation of the tasks to particular ... -
Credit Card Transactions Fraud Detection, and Machine Learning: Modelling Time with LSTM Recurrent Neural Networks
(University of the Western Cape, 2007)In recent years, topics such as fraud detection and fraud prevention have received a lot of attention on the research front, in particular from plastic card issuers. The reason for this increase in research activity can ... -
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 ... -
KernTune: Self-tuning Linux Kernel Performance Using Support Vector Machines
(University of the Western Cape, 2006)Self-tuning has been an elusive goal for operating systems and is becoming a pressing issue for modern operating systems. Well-trained system administrators are able to tune an operating system to achieve better system ... -
Digital watermarking methods for data security and authentication
(University of the Western Cape, 2008)Throughout history people have tried to develop methods to secure the exchange of information. Due to the influence of the information technology revolution, protecting data of different types has become as essential ... -
The Efficacy of the Eigenvector Approach to South African Sign Language Identification
(University of the Western Cape, 2010)The communication barriers between deaf and hearing society mean that interaction between these communities is kept to a minimum. The South African Sign Language research group, Integration of Signed and Verbal Communication: ... -
A comparative evaluation of 3d and spatio-temporal deep learning techniques for crime classification and prediction
(University of Western Cape, 2021)This research is on a comparative evaluation of 3D and spatio-temporal deep learning methods for crime classification and prediction using the Chicago crime dataset, which has 7.29 million records, collected from 2001 ... -
Chereme- Based Recognition of Isolated, Dynamic Gestures from South African Sign Language with Hidden Markov Models
(University of the Western Cape, 2006)Much work has been done in building systems that can recognise gestures, e.g. as a component of sign language recognition systems. These systems typically use whole gestures as the smallest unit for recognition. Although ... -
Synergistic use of promoter prediction algorithms: A choice for small training dataset?
(University of the Western Cape, 2000)This chapter outlines basic gene structure and how gene structure is related to promoter structure in both prokaryotes and eukaryotes and their transcription machinery. An in-depth discussion is given on variations types ... -
A Digital Identity Management System
(University of the Western Cape, 2007)The recent years have seen an increase in the number of users accessing online services using communication devices such as computers, mobile phones and cards based credentials such as credit cards. This has prompted most ... -
South African Sign Language Recognition Using Feature Vectors and Hidden Markov Models
(University of the Western Cape, 2010)This thesis presents a system for performing whole gesture recognition for South African Sign Language. The system uses feature vectors combined with Hidden Markov models. In order to construct a feature vector, dynamic ... -
