Abstract :
Eddy current pulsed thermography (ECPT) is one of the most potential techniques in the area of non-destructive testing. In this paper, an independent components (ICs) adjustment approach based on Independent Component Analysis (ICA) is proposed to apply for ECPT analysis in non-destructive testing. How to recognize the significant ICs in the mixing model is analyzed and discussed. This method can help to select the important and significant ICs, in order to ensure construct the low-dimensional sub-feature space. The experimental result can be utilized to validate the adjustment approach for choosing important ICs and demonstrate the effectiveness of the proposed method in ECPT.
