A Novel Method to Estimate the Damage Severity Using Spatial Wavelets and Local Regularity Algorithm

In the process of structural damage detection using continuous wavelet transform (CWT), the perturbation or damage is located by identifying the defects locally in the input signal data. In this work the damage identification procedure using continuous wavelet transform is developed. This method is...
