#5 Preprint: Texture Matched Wavelet Filterbanks

Title: Orthogonal and Biorthogonal Texture Matched Wavelet Filterbanks for
Hierarchical Texture Analysis

Appeared in Signal Processing, No. 54, S. 1-22, Elsevier Verlag,
Niederlande, 1996

Author: Thomas Greiner

The paper deals with the application of the wavelet transform to
hierarchical texture analysis. The main goal is the design of
texture-matched FIR filterbanks as the dyadic (2 channel) orthogonal
and the M channel biorthogonal wavelet filterbanks. The approach
represents an extension of the mathematically-oriented design methods
for multirate and wavelet filterbanks. The cascaded application of the
filterbanks results in a critically, by the factor M × M (with M >=
2) downsampled, pyramidal representation of the textured image. The
performance of these new filters discriminating textures is compared
with the classical wavelet approaches on Brodatz´s textures.
