Abstract
Background: T1, T2 and PD weighted images are the three bands of magnetic resonance image and they provide complementary information of the structure of the part being imaged. It is more useful for diagnosis and analysis if they are fused into MRI triplet.
Discussion: This paper proposes a novel fusion method using Selective Frequency Localization Contourlet Transform to combine these three bands into one.
Conclusion: From the qualitative and quantitative evaluation using average pixel intensity, standard deviation, mutual information and edge information based objective criteria, the fused image is found to be more informative.
Keywords: Magnetic resonance images, cycle spinning, contourlet transform, spatial frequency, sum modified laplacian, fusion method.
