Abstract

This paper presents a novel multi-modal medical image fusion algorithm based on wavelet transform. The algorithm is improved based on the rule of usual local region-energy fusion, expanding the fusion to low-frequency coefficient processing, and adding direction weighted operator based on different sub-frequency band reflecting image features. Experiments results of CT and MRI image fusion proved that the algorithm can get a better fusion effect than other usual fusion methods.
