Improved Guided Image Fusion for Magnetic Resonance and Computed Tomography Imaging

الملخص EN

Improved guided image fusion for magnetic resonance and computed tomography imaging is proposed.

Existing guided filtering scheme uses Gaussian filter and two-level weight maps due to whichthe scheme has limited performance for images having noise.

Different modifications in filter (basedon linear minimum mean square error estimator) and weight maps (with different levels) are proposedto overcome these limitations.

Simulation results based on visual and quantitative analysis show thesignificance of proposed scheme.
