2010 is the centenary (with 1 % imprecision) of the Haar wavelet (or Haarlet). Oddly, it possesses an anagram, raah. According to Urban Dictionary, raah denotes:
A richly dressed person, usually with big hair and are commonly situated in Surrey. They enjoy prancing around in Ralph Lauren, Jack Wills and Abercrombie & Fitch. Their grooming and hair can be described as messy, but stylish.
To celebrate such a birthday, everybody is invited to contribute to the call for paper to Elevier Signal Processing: Advances in Multirate Filter Bank Structures and Multiscale Representations, with a 15 February 2010 deadline.
The CfP is featured at several other places:
and last but not least at Nuit Blanche:
Thank you Igor.
Not exclusive topics: Sampling theory, compressive sensing . Sparse representations . Multiscale models . Multiscale processing: interpolation, inpainting, restoration . Wavelet shrinkage and denoising . Oversampled filter banks, discrete frames . Rational and non-uniform multirate systems . Directional, steerable filter banks and wavelets . Nonlinear filter banks . (Multidimensional) filter bank design and optimization . Hybrid analog/digital filter banks . Fast and low-power schemes (lifting, integer design) . Multiscale and multirate applications to source and channel coding, equalization, adaptive filtering,...
The english version of the founding paper On the Theory of Orthogonal Function Systems (Zur Theorie der orthogonalen Funktionen-Systeme), translated for the magnificent collection of papers in Fundamental Papers in Wavelet Theory edited by Christopher Heil and David F. Walnut, is made available at WITS: Haarlet.
Matlab codes for Multivariate Dual Tree Wavelet Denoising (based on Stein's principle), were created to illustrate and reproduce the results presented in:
A nonlinear Stein-based estimator for multichannel image denoising

IEEE Transactions on Signal Processing, August 2008, Volume 56, Issue 8, p. 3855-3870
They have been made available at Research codes, and can be used them freely for research purposes.
Finally, in homophonia memoriam, to Ar-lette Duval, in loving memory to her vanishing souvenirs (thanks Alois), totally ceased today.
