Autonomous facial expression recognition using the facial action coding system
de la Cruz, Nathan (University of the Western Cape, 2016)The South African Sign Language research group at the University of the Western Cape is in the process of creating a fully-edged machine translation system to automatically translate between South African Sign Language and ... -
Avatar animation from SignWriting notation
Abrahams, Kenzo (University of the Western Cape, 2015)The SASL project at the University of the Western Cape is in the process of developing a machine translation system that can translate fully-fledged phrases between South African Sign Language (SASL) and English in ... -
A comparative evaluation of 3d and spatio-temporal deep learning techniques for crime classification and prediction
Matereke, Tawanda Lloyd (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 ... -
A comparison of machine learning techniques for hand shape recognition
Foster, Roland (University of the Western Cape, 2015)There are five fundamental parameters that characterize any sign language gesture. They are hand shape, orientation, motion and location, and facial expressions. The SASL group at the University of the Western Cape has ... -
Faster upper body pose recognition and estimation using compute unified device architecture
Brown, Dane (University of Western Cape, 2013)The SASL project is in the process of developing a machine translation system that can translate fully-fledged phrases between SASL and English in real-time. To-date, several systems have been developed by the project ... -
A framework for the analysis of discrete irregular patterned sequential datasets
Dandajena, Kudakwashe (University of the Western Cape, 2023)Trial-and-error is often used for developing new deep learning models. There is no systematic procedure for improving existing models for predicting irregular sequential time-series. This research developed a systematic ... -
Geo-physical parameter forecasting on imagery{based data sets using machine learning techniques
Hussein, Eslam (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 ... -
Hand shape estimation for South African sign language
Li, Pei (University of the Western Cape, 2012)Hand shape recognition is a pivotal part of any system that attempts to implement Sign Language recognition. This thesis presents a novel system which recognises hand shapes from a single camera view in 2D. By mapping the ... -
Handwritten alphabet character recognition using audio signatures and machine learning
Beck, Bruce (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 ... -
An integrated sign language recognition system
Nel, Warren (University of Western Cape, 2014)Research has shown that five parameters are required to recognize any sign language gesture: hand shape, location, orientation and motion, as well as facial expressions. The South African Sign Language (SASL) research ... -
A robust audio-based symbol recognition system using machine learning techniques
Wu, Qiming (University of the Western Cape, 2020-02)This research investigates the creation of an audio-shape recognition system that is able to interpret a user’s drawn audio shapes—fundamental shapes, digits and/or letters— on a given surface such as a table-top using a ... -
Robust facial expression recognition in the presence of rotation and partial occlusion
Mushfieldt, Diego (University of Western Cape, 2014)This research proposes an approach to recognizing facial expressions in the presence of rotations and partial occlusions of the face. The research is in the context of automatic machine translation of South African Sign ... -
Robust South African sign language gesture recognition using hand motion and shape
Frieslaar, Ibraheem (2014)Research has shown that five fundamental parameters are required to recognize any sign language gesture: hand shape, hand motion, hand location, hand orientation and facial expressions. The South African Sign Language ... -
South African Sign Language Hand Shape and Orientation Recognition on Mobile Devices Using Deep Learning
Jacobs, Kurt (University of the Western Cape, 2017)In order to classify South African Sign Language as a signed gesture, five fundamental parameters need to be considered. These five parameters to be considered are: hand shape, hand orientation, hand motion, hand location ... -
The use of mobile phones as service-delivery devices in sign language machine translation system
Ghaziasgar, Mehrdad (University of the Western Cape, 2010)This thesis investigates the use of mobile phones as service-delivery devices in a sign language machine translation system. Four sign language visualization methods were evaluated on mobile phones. Three of the methods ...
