Abstract: Multimodal imaging techniques of the same organ help in getting anatomical as well as functional details of a particular body part. Multimodal imaging of the same organs can help doctors diagnose a disease cost-effectively. In this paper, a hybrid approach using transfer learning and discrete wavelet transform is used to fuse multimodal medical images. As the access to medical data is limited, transfer learning is used for feature extractor and save training time. The features are fused with a pre-trained VGG19 model. Discrete Wavelet Transform is used to decompose the multimodal images in different sub-bands. In the last phase, Inverse Wavelet Transform is used to obtain a fused image from the four bands generated. The proposed model is executed on Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) datasets. The experimental results show that the proposed approach performs better than other approaches and the significance of the obtained fused image is measured using qualitative metrics.
