Author:Du Plessis, WP; Odendaal, JW; Joubert, JDate:Sep 2009An extended and rigorous analysis of retrodirective cross-eye jamming in a radar system scenario is presented. This analysis removes the approximations that limit the validity of other analyses of cross-eye jamming. These results imply that ...Read more
Author:Magubane, Z; Tarwireyi, P; Abu-Mahfouz, Adnan MI; Adigun, MDate:Nov 2021The Internet of Things is a network of devices that sense and communicate the sensed data over the internet without human intervention. These devices are resource constrained, perform poor in a complex network. Routing becomes a significant ...Read more
Author:Brown, Dane; Bradshaw, KDate:Sep 2016The feature-level, unlike the match score-level, lacks multi-modal fusion guidelines. This work demonstrates a practical approach for improved image-based biometric feature-fusion. The approach extracts and combines the face, fingerprint and ...Read more
Author:Mdakane, L; Van den Bergh, FDate:Nov 2012Despite the fact that image texture features extracted from high-resolution remotely sensed images over urban areas have demonstrated their ability to distinguish different classes, they are still far from being ideal. Multiresolution grayscale ...Read more
