title = "Investigation of a new feature for angular defect quantification by eddy current pulsed thermography",
abstract = "Eddy current pulsed thermography (ECPT) as one of the emerging NDT&E techniques has been used for the evaluation of the integrity of rail tracks, especially for rolling contact fatigue (RCF) or angular defect detection and quantification. This paper proposed a new feature for angular defect quantification. Specifically, first-order differential of the transient thermal response was first obtained. Then a new feature derived from the first-order differential result was used to quantify the length of the angular slot. R-squared value and 2-norm of the residual were used to evaluate and compare the fitted linear relationship between different extracted features and the angular slot lengths. Through the comparison with other features, the strength and limitation of this new feature were summarized.",
