Abstract: - Image fusion is a process of combining the complementary information from two or more images into a single highly informative image. The resulting fused image contains more information than both the input images. In this paper DMWT algorithm for fusing two different modality medical images and different quantitative metrics are calculated. The images obtained from different medical imaging techniques such as Computer Tomography (CT) and Magnetic Resonance (MR) images are fused into a new image to improve the information quality. In the present fusion algorithm, the input images from two different modalities such as CT and MR are initially registered and then transform namely Multi-Wavelet transform is applied on the input images. Finally the resultant images are fused using various fusion techniques. Qualitative metrics for resultant image such as entropy, standard deviation are calculated.
