Abstract
A single channel blind source separation is proposed to process the Eddy Current Pulsed Thermography (ECPT) image sequences. The proposed method enables the detection automatically extract valuable spatial and time patterns according to the whole transient response behavior without any training knowledge. In addition, it has the potential to automatically identify defect patterns and quantify the defects. In this study, both mathematical and physical models are discussed and linked. The basis of the selection of separated spatial and time patterns is also presented. In addition, a natural crack is applied to validate the proposed method.
