Signal and Image Processing Group (SIPG)

Research at the Signal and Image Processing Group (SIPG) focus on the development of fundamental theory for signal processing on manifolds, e.g., performance bounds, optimization algorithms, filtering, manifold learning. Application areas are: wireless communications, including blind equalization and source separation; underwater, including acoustic communications and video compression and analysis; time-frequency analysis; image analysis, including statistical modelling; and video processing, including motion estimation, tracking of deformable models and inference of 3D structure.
