Mathematics in Geosciences, September 2001 - June 2002
6 hours of lectures, February 18-20, 2002
All lectures in Lind 409
In this 3-day mini-course the application of the wavelet and
related transforms to seismology will be discussed. Attention
will be paid to characterization as well as to non-linear solution
of linear inversion problems, such as denoising and deconvolution.
First a brief overview of (exploration) seismology will be given,
followed by a review of the continuous wavelet transform as
a tool to characterize the scaling of broadband upper sedimentary
records (well-log data). Mallat's Wavelet Transform Modulus
Maxima method will be introduced to calculate the Hölder
regularity as well as the multifractal singularity spectra.
Secondly, methods will be discussed that aim to estimate local
coarse-grained Hölder exponents from essentially bandwidth
limited seismic data. These methods consist of extensions of
the Modulus Maxima framework and of a Matching Pursuit Algorithm
with Fractional Spline Wavelet Packets as a dictionary. Finaly,
examples will be shown how to apply basis function expansions
to the non-linear solution of linear inverse problems.
