EEE Expo 2012 School of Electrical and Electronic Engineering - The University of Adelaide Slide 0 Signal Information Processing Brian Ng

EEE Expo 2012 School of Electrical and Electronic Engineering - The University of Adelaide Slide 1 Multi-rate Signal Processing and Wavelets Fundamental research on multi-rate filter banks –Multi-resolution analysis –Rational cases Applications in time-frequency analysis of signals in numerous fields –Radar signal processing –Time-domain THz spectroscopy

EEE Expo 2012 School of Electrical and Electronic Engineering - The University of Adelaide Slide 2 Information Extraction Sparse representations –Many real life signals afford sparse representations –Exploited for reconstructions from incomplete measurements –Application in many fields, e.g. detection, rapid measurements Real world signals contain much useful information –Often obscured by noise, interference … etc –Processing techniques become critical –Current projects: –Breast cancer detection –railway bearing condition monitoring –Environmental discovery from vision
