Nonadaptive, semi-adaptive and adaptive approaches to signal processing problems in nondestructive evaluation

In signal processing problems associated with estimation or pattern recognition in nondestructive evaluation (NDE), the degree of adaption can vary between wide limits, and is related to the availability or usability of a priori information. We will discuss several examples of NDE signal processing problems involving varying degrees of adaption, namely: (1) a completely nonadaptive approach to the extraction of low frequency properties of scatterers, (2) a semi-adaptive approach to the same problem, and (3) a completely adaptive approach to the classification of acoustical emission signals.
