Abstract

In the field of medical imaging Image fusion is an important application for extracting complementary information from different modality In this work we propose a fusion algorithm using CDF9 7 wavelet based on lifting scheme with specified fusion rules to combine pairs of multispectral Magnetic Resonance Imaging MRI such as T1 T2 The experimental results of brain tumor show that the proposed algorithm preserves both edge and component information and also increases the efficiency of tumor detection The parameters like mutual information MI entropy EN and spatial frequency SF standard deviation SD are calculated to evaluate performance of proposed algorithm Finally the results are compared with existing methods
