Defects in magnetizable materials can be detected and evaluated
by measuring electromagnetic data. The evaluation of this data relies on
effective denoising techniques. In this talk, two types of denoising
techniques for two different types of noise are presented. The first is
based on wavelets and uses the stochastic denoising procedure of Donoho
and Johnstone, the second one is based on curvelets and nonlinear
approximation. Examples will be provided to demonstrate the issues
involved and to validate the algorithms.
