LNLA 2008 - Lausanne, Switzerland
The 2008 International Workshop on Local and Non-Local Approximation in Image Processing
Tampere International Center for Signal Processing (TICSP) has been continuously aiming at organizing high-profile international workshops on advanced and emerging topics of modern signal processing. With this aim, TICSP organized a series of international Workshops on Spectral Methods and Multirate Signal Processing held in Moscow, Russia (2007), Florence, Italy (2006), Riga, Latvia (2005), Vienna, Austria (2004), Barcelona, Spain (2003), Toulouse, France (2002), and Pula, Croatia (2001). These workshops came as a follow up of International Workshops on Transforms and Filter Banks, first arranged in Tampere, Finland in 1998, and second time in Brandenburg, Germany in 1999.
All these workshops have brought together leading experts in diverse areas such as spectral and transform methods, filterbanks, and multirate signal processing in a stimulating and relaxed atmosphere to discuss the most important issues in these fields. The workshops have given a unique opportunity to examine the deep interconnections between transforms, filter banks, and other signal representations as well as to recognize new and emerging fields of research. Partly, the discussions held during these workshops lead to the observation that new and dramatic developments in image processing have been happening. While wavelet expansions have finally established themselves as the prototype of a modern efficient approach to signal processing applications, adaptive local and non-local approximations have emerged as novel surprisingly powerful tools for image analysis, restoration, compression, and enhancement. The current state-of-the-art in image processing exhibits a plethora of these diverse techniques, which are apparently very different but deeply and intimately related through concepts such as sparsity, redundancy, compressibility, and self-similarity.
With the intention to follow and document these latest advances, this year TICSP organizes the first International Workshop on Local and Non-Local Approximation in Image Processing (LNLA), held in Lausanne, Switzerland.
As with the previous workshops, we aim at generating stimulating interaction between people with diverse yet complementary background and expertise. One of our main goals is to reach a unified view of the different approaches and generate ideas about novel image models which can explain and drive future developments. Emphasis is laid on transferring theoretical results to practical applications and on building long-term cooperation between teams. We hope the marvellous venue of Lausanne will inspire the fruitful exchange of new ideas and future collaboration.
We wish to thank the sponsors, IEEE SP & CAS Chapter of Finland, the European Association for Signal Processing (EURASIP), and Tampere International Center for Signal Processing, for their support. We especially thank the authors for their high quality contributions.
