Quaternion adaptive line enhancer (QALE) has been proposed recently for the recovery of two- (2-D) or three-dimensional (3-D) periodic signals from their noisy mixtures [1] with the help of quaternion-valued adaptive filtering theory. Similar to the traditionall-D [2] version, QALE, relies mainly on…
This work addresses the problem of segmentation in time series data with respect to a statistical parameter of interest in Bayesian models. It is common to assume that the parameters are distinct within each segment. As such, many Bayesian change point detection models do not exploit the segment par…
The advent of Internet of Things, has resulted in the development of infrastructure for capturing and storing data from domains ranging from smart devices (e.g. smartphones) to smart cities. This data is often available publicly and has enabled a wider range of data consumers to utilise such data se…
The recent introduction of η-Hermitian matrices A = A <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">ηH</sup> has opened a new avenue of research in quaternion signal processing. However, the exploitation of this matrix structure has been limited, perh…
