Preface

Wavelet analysis is one of the most effective solutions to overcome the drawbacks of
Fourier analysis, and since the seminal work of Ingrid Daubechies was published in
the late 1980s, it has been applied very successfully in various branches of science and
engineering. The fractional wavelet techniques started to play an important role in
data treatment corresponding to complex systems during the last decade.
The wavelet transform and it generalization started to be an efficient mathematical
tool which has been widely used to investigate a signal in a time-frequency
representation to allow analyzing the parts of interest individually.
As it is well known the main difficulty in processing the biological signals is their
extreme variability and the requirement to analyse on a case by case basis. The wavelet
transform is recognized as an useful tool in the signal analysis corresponding to the
biological data as well as to the complex seismic data.
This book aims to show the range of applications of wavelet analysis to data from the
field of biology and geosciences.
Specifically, the book contains chapters showing how the wavelet transform was used
for the analysis of EEG signals in patients with oral communications,how it was used
to investigate the energy distribution of the EEG signal components as well as its use
for the dimensional reduction in a gait recognition framework.
One of the chapters shows how we can convert EEG activity into cursor movement by
a brain computer interface using an appropriate feature extraction scheme. The
detection data of mammary carcinoma processing method based on the wavelet
transformation was presented. The applications of the wavelet method in sport and
hand palm texture biometric identification and verification were illustrated.
Improvement of shimmer parameter of oesophageal voices using wavelet transform
and the application of this method for textile material feature extraction is another
interesting topic covered by this book. The powerful utilization of the wavelet
transform and its varieties in two important applications, namely biometrics and non-
destructive testing is explained in detail.
X Preface

In this book the reader can find new methods involving two spherical multiscale
transforms, the wavelet and the curvelets, and the design for restoration of spherical
data with noise following a Poisson distribution.
The book ends with two applications of 1D and 2D wavelet transforms used in
treatments of the geophysical signals.
I strongly believe that the chapters of this book will be of great help for graduate and
postgraduate students, as well as for researchers who will get a general view of the
powerful wavelet method and its applications in treatment of biological and
geoscience data .
