MRI/SPECT Image Fusion of Brain Based on Multi-Scale Wavelet Decomposition

This paper presents a study on the possibilities offered by the multi-scale wavelet decomposition in the medical image fusion of the brain obtained by MRI and SPECT technology. The influences of various discrete wavelet functions by which the decomposition was obtained and the corresponding level at which it was constructed are analysed. The implemented study and the results obtained using real images would be useful in making a more precise diagnosis.
