Signal-to-Noise Ratio Improvement Based on the Discrete Wavelet Transform in Ultrasonic Defectoscopy
Original language description
A new method for filtering of ultrasonic signal using discrete wavelet transform is presented. The method is based on the thresholding of wavelet coefficients using local threshold related to the standard deviation of the decomposed signal. The proposedapproach was tested on coarse grain materials used for airplane engines and on simulated signals with artificial noise.
