Articulated structure from motion
Scheffler, Carl (University of the Western Cape, 2004)The structure from motion (SfM) problem is that of determining 3-dimensional (3D) information of a scene from sequences of 2-dimensional (2D) images [59]. This information consists of object shape and motion and relative ... -
Chereme-based recognition of isolated, dynamic gestures from South African sign language with Hidden Markov Models
Rajah, Christopher (University of the Western Cape, 2006)Much work has been done in building systems that can recognize gestures, e.g. as a component of sign language recognition systems. These systems typically use whole gestures as the smallest unit for recognition. Although ... -
Data mining, fraud detection and mobile telecommunications: call pattern analysis with unsupervised neural networks
Abidogun, Olusola Adeniyi (University of the Western Cape, 2005)Huge amounts of data are being collected as a result of the increased use of mobile telecommunications. Insight into information and knowledge derived from these databases can give operators a competitive edge in terms of ... -
End-to-end single-rate multicast congestion detection using support vector machines
Liu, Xiaoming (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 ... -
Metric of trust for mobile ad hoc networks using source routing algorithms
Umuhoza, Denise (University of the Western Cape, 2006)This thesis proposed and presented technical details of new probabilistic metrics of trust in the links wireless ad hoc networks for unobservable communications. In covert communication networks, only the end nodes are ... -
Recognition of facial action units from video streams with recurrent neural networks : a new paradigm for facial expression recognition
Vadapalli, Hima Bindu (University of the Western Cape, 2011)This research investigated the application of recurrent neural networks (RNNs) for recognition of facial expressions based on facial action coding system (FACS). Support vector machines (SVMs) were used to validate the ...
