Embodiment 1
[0053] The invention discloses a multimodal fusion image classification method based on modal distance constraints, such as figure 1 As shown, the method includes the steps of:
[0054] The first step, obtaining data, specifically: obtaining rs-fMRI data and DTI data of a plurality of subjects, and performing preprocessing, obtaining preprocessed rs-fMRI data and preprocessed DTI data;
[0055] The second step is to construct the feature vector of the brain function network and the feature vector of the brain structure network. The details are as follows:
[0056] The construction of the brain function network feature vector is based on the preprocessed rs-fMRI data, specifically: using the automatic anatomy label template to generate 90 cortical and subcutaneous nuclei regions, and removing the cerebellum; The Pearson correlation coefficient of the region to the average time series; the nodes in the brain function network are defined as ninety cortical and subcutaneous nucle...
