In this article, the Contourlet-based image fusion method of digital neutron radiation image and X-ray radiograph is proposed. As one of the multi-scale geometric analysis, Contourlet transform is full of application potentials in the field of image process due to its good capability of representing high dimensional singularity of image. Meanwhile, in order to overcome the shortcoming of pixel-based fusion, this method proposed realizes the local adaptive fusion through Neighborhood Homogeneity Measurement (NHM). Experiments show that this fusion method retains more image detail and therefore provides more accurate information than traditional image fusion methods. It is proved to be a novel idea for the complementary application of neutron radiation imaging and X-ray radiograph
