Multimodal Medical Image Fusion Using Discrete Fractional Wavelet Transform (DFRWT) with Non-subsampled Contourlet Transform (NSCT) Hybrid Fusion Algorithm

Abstract

In a day to day clinical practice a multimodal medical imaging becomes a general part in medical field. Multimodality image fusion is playing a significant role in disease diagnostics and post treatment analysis. An efficient image fusion system based on DFRWT—NSCT hybrid technique is proposed in this paper. The comparative analysis between the conventional and hybrid technique is presented. The proposed fusion system tested and evaluated with various performance metrics. Experimental results explained that the proposed technique achieves a superior visual quality for accurate disease diagnosis.
