Eddy current pulsed thermography (ECPT) has been applied for a wide range of conductive materials. The enhancement of thermography to detect the defects is also important. This paper proposes an independent component analysis (ICA) fusion method based fuzzy algorithm to process the thermography images. In ICA, three kinds of contrast function are applied to obtain the different ICs respectively. Then, the corresponding fused ICs are obtained by the fuzzy fusion algorithm. Meanwhile, the kurtosis of each ICs before and after fusion are computed to evaluate the performance of the proposed method. In addition, an experiment is utilized to show the benefits of the proposed ICA fusion method.
