Recent advances in instrumentation and signal processing allow the acquisition of eddy current NDE signal in the form of c-san images. A technique is presented in this paper to enhance eddy current inspection based on multi-spectral, multi-temporal, and multi-resolution image fusion. The developed algorithm is motivated by human eye perception of colored objects. Mathematically it is based on the IHS transform, as well as the shift invariant wavelet analysis. Quality of resulting fusion images is evaluated based on statistical image quality metrics.
