In this paper, a method based on the discrete wavelet transform is proposed for eddy current image fusion. This method mainly involves two steps: selection of the proper wavelet filters and level of decomposition using formulated parameter, and selection of the proper fusion criterion in wavelet sub-band. The main aspect of the proposed method concentrates on elimination of noise while retaining defect information. This method fuses the eddy current images at two different frequencies from… CONTINUE READING
