An Improved Feature Parameter Extraction Algorithm of Composite Detection Method Based on the Fusion Theory
An improved feature parameter extraction algorithm is proposed in this study to solve the problem of quantitative detection of subsurface defects. Firstly, the common feature parameters from the differential signal of pulsed eddy current and ultrasonic are extracted in time domain and frequency doma...
