Abstract :
Fast localization and classification of defects and structure elements in the defectoscopy of steam generator tubes is the field where application of wavelet transformation is very perspective. Presented paper recapitulates possible applications of wavelet transformation in different subtasks of process analysis of output signal from measurement probe based on eddy-currents.
