Embodiment 1
[0035] Such as figure 1 As shown, this embodiment provides a classification method for Alzheimer's disease based on anatomical landmarks and residual networks, including:
[0036] Step 1. After tissue segmentation and modulation of the training image set, the gray matter image is obtained;
[0037] Step 2. Perform a two-sample t-test on the voxels of the Alzheimer's disease image and the normal subject image in the training image set, and identify anatomical landmarks with a preset significance level threshold;
[0038] Step 3, extracting the gray matter feature block of the gray matter image centered on the obtained anatomical landmark;
[0039] Step 4. Connect the gray matter feature blocks, input the obtained synthetic blocks into the residual network model for feature extraction, use the features extracted by the residual network model as the input of the classifier, and test the Alzheimer's disease patients in the test image set Classified with normal subjects.
