Advanced Digital Signal Processing


12-16 February 2007

 

THE COURSE

This intensive course is designed to give an appreciation of the theory and application of digital signal processing. Starting at introductory level, the course covers fundamental theory including the Discrete Fourier Transform, and Fast Fourier Transform algorithms; it then progresses into the design of digital filters.

The theory and applications of adaptive filters is covered, and the course then moves into a discussion of statistical signal processing, including Bayes estimators, and Wiener filtering. There will be exercises to show the use of state-of-the-art DSP simulation software in the solution of signal processing problems.

Practical work reinforces the theoretical concepts introduced.

THE LECTURERS

The course is presented by some of the leading academics in the field of Digital Signal Processing at the University of Surrey.

Dr Ted Chilton

Dr Ted Chilton held the Racal Research Fellowship for four years from 1984-1988 and is now a Senior Lecturer with the Centre for Vision, Speech and Signal Processing (CVSSP). His specialist areas are in speech recognition and the application of transforms to a variety of signal processing problems.

Professor Josef Kittler
Professor Josef Kittler is Director of CVSSP at the University of Surrey. He has more than 30 years of experience in pattern recognition, using both statistical and neural network approaches. He has worked on various theoretical aspects of Pattern Recognition and on many applications including System Identification, Automatic Inspection, ECG diagnosis, Remote Sensing, Robotics, Speech Recognition, Character Recognition, Document Analysis, Biometrics, Image and Video Retrieval and Computer Vision. He has co-authored a book with the title ``Pattern Recognition: a statistical approach'' and published more than 400 papers. He is a member of the Editorial Boards of Pattern Recognition Journal, Image and Vision Computing, Pattern Recognition Letters, Pattern Recognition and Artificial Intelligence, Machine Vision and Applications, and Pattern Analysis and Applications.

Professor Maria Petrou

Professor Maria Petrou received her BSc in Physics from the Aristotle University of Thessaloniki, Greece, and her PhD in Astronomy from the University of Cambridge, UK. She has been working on Image analysis since 1986 and has published more than 250 papers, on Astronomy, Low Level Vision, Feature Extraction, Texture Analysis, Markov Random Fields, Multiresolution optimisation, Probabilistic Relaxation, Colour, Remote Sensing, Industrial Inspection, Medical Signal Processing, etc. She has co-authored a book ``Image Processing: the fundamentals'' published by John Wiley. She is a Chartered Engineer, member of IEEE, Fellow of IEE, Fellow of IAPR. She is Honorary Editor at IEE Electronic Letters and the Treasurer at IAPR.

Dr Philip Jackson

Dr Philip Jackson is lecturer of speech and audio processing in CVSSP, with ten years' experience of signal processing since graduating with honours from Cambridge University Engineering Department. In industry, he developed Active Noise Cancellation systems for commercial aircraft, including the world's first. His PhD, awarded in 2000 by the University of Southampton, was on Acoustic Modelling and Speech Analysis of consonants. He was then research fellow at the University of Birmingham with a project to apply articulatory methods in Automatic Speech Recognition that was rated "outstanding" by EPSRC, before coming to Surrey.
