Abstract: The reassigned wavelet scalogram analysis method can improve the aggregation of scalogram, reduce interference terms, and be understood easily to some extent. Aiming at the deficiency of using Metal Magnetic Memory Testing to recognise pipeline defect, the reassigned wavelet scalogram analysis method is put forward to analysis the Metal Magnetic Memory Testing signal. The experimental research proves that the reassigned wavelet scalogram effectively used for Pipeline Defect Recognition by Metal Magnetic Memory Testing.
