Paul Fieguth

Paul Fieguth is a Professor, as well as Chair of the Systems Design Engineering department. He is also the Director of the Vision and Imaging Processing Lab at the University of Waterloo.

His main areas of research lie in multiscale statistical modelling and remote sensing. Dr. Fieguth is concentrating on the theory development and understanding of scale recursive estimation algorithms for multi-resolution stochastic processes. Such algorithms use a statistically meaningful strategy to break large estimation problems into smaller pieces, leading to vast improvements in efficiency.

While these algorithms are capable of extremely fast assimilation of data, it is difficult to determine the appropriate multiscale model for a given application of interest. The model assumes a time-invariant model underlying the measurements, and the estimates produced by the model often possess certain multiscale artifacts. Dr. Fieguth aims to address these limitations in the context of a specific data assimilation problem involving a time-varying system: the world's oceans’ surface shape. This approach has allowed him and his research team to contribute to an oceanography issue, while simultaneously providing access to an extensive data set on which to test their algorithms.

Dr. Fieguth’s work in remote sensing is conducted in collaboration with researchers in oceanography who supply physical models, observational data, and the scientific expertise to ensure that meaningful answers are being computed to meaningful problems. Past and ongoing remote sensing efforts include ocean altimetry (production of ocean-surface maps), ocean hydrography (estimation of volumetric temperature fields), acoustic tomography (estimation of large-scale oceanographic features from measurements of sound propagation), and geodesy (determining high-resolution features of the earth's gravitational field from ocean-surface features).
