The Way of Medical Image Fusion Usingthe Legendre Orthogonal Moment
基于Legendre矩的CT及MR医学图象融合方法

In this paper, we presented the way to register or fuse CT and MR multi-modality image based on the Legendre moment. Because Legendre moment has the merits of orthogonal and minimal information redundancy, by using it, we can find the center of mass of CT and MR images, calculate the scale factor of these images, then the translation and rotation of these images can be performed, these images are registered precisely;Optimizing the Legendre moment's algorithm, we quickened up the registration or fusion of CT and MR images. This method proved to be effective,simple in the registration of multi-modality medical images in our experiment. Legendre moment is also important to the registration and fusion in multi-modality medical image, and in the radiotherapy treatment program system.
