Abstract:Eddy Current Pulsed Thermography (ECPT) is a emerging Non-Destructive Testing and Evaluation (NDT&E) technique, has been applied for a wide range of conductive materials. In this paper, a single channel blind source separation is proposed to process the ECPT image sequences. The proposed method enables (i) automatically extract valuable spatial and time patterns according to the whole transient response behavior without any training knowledge, (ii) automatically identify defect patterns and quantify the defects, (iii) provide guidelines of choosing the optimal contrast functions
