    MRI Volume Fusion Based on 3D Shearlet Decompositions by Chang Duan, Shuai Wang, Xue Gang Wang, Qi Hong Huang

    Published 2014-01-01
    “…And this method is evaluated upon MRI T2* and quantitative susceptibility mapping data of 4 human brains. Both the perspective impression and the quality indices indicate that the proposed method has a better performance than conventional 2D wavelet, DT CWT, and 3D wavelet, DT CWT based fusion methods.…”
