Specific Example 1

[0037] A classification method of Alzheimer's disease based on deep forest includes the following steps:

[0038] Step 1: Use the MRI image for detecting Alzheimer's disease as the input of the multi-granularity scan, the output of the multi-granularity scan is connected to the cascade forest, and the cascade forest outputs a class vector of the MRI image to complete the deep forest model Constructed, the classification results of the MRI image include Alzheimer's disease (AD), mild cognitive impairment (MCI) and normal people (NC), and the class vector is the maximum probability value in the MRI image class.

[0039] Step 2: Preprocess the MRI images of several known categories, that is, perform AC-PC origin correction on the MRI image; segment each corrected MRI image to obtain an MRI gray matter image; normalize the MRI gray matter image to A unified MNI template makes the size of each MRI gray matter image uniform; smoothing and down-sampling the standardize...

Abstract

The invention discloses an Alzheimer's disease classification method based on a depth forest, and belongs to the field of medical image classification and prediction. The method comprises the steps: taking an MRI image of the detection of the Alzheimer's disease as the input of the multi-granularity scanning, enabling the output of the multi-granularity scanning to be connected with a cascading forest, enabling the cascading forest to output one class vector of the MRI image, and completing the construction of a depth forest model; carrying out the preprocessing of a plurality of MRI images of known types; extending the depth forest model by one level, and carrying out the training and testing through the preprocessed MRI image: completing the training if a testing result is not improved remarkably, or else extending to the next level and continuing the training; inputting the preprocessed to-be-classified MRI image into the trained depth forest, and outputting and obtaining a classification result of the MRI image. The method greatly improves the recognition rate of the Alzheimer's disease.

Description

technical field [0001] The invention relates to the fields of medical image classification, pattern recognition and machine learning, in particular to a deep forest-based Alzheimer's disease classification method for classifying and judging Alzheimer's disease. Background technique [0002] Today, with the vigorous development of image processing technology, pattern recognition and machine learning theories and methods, medical image processing, as one of the fields most closely related to human life, has attracted more and more attention following in the footsteps of artificial intelligence. The classification of Alzheimer's disease is an important branch in the field of medical image classification. It is of great significance in the computer-aided diagnosis of Alzheimer's disease, especially in the early diagnosis of the disease and the timely control of the disease deterioration. [0003] MRI (Magnetic Resonance Imaging) images can provide a wealth of brain tissue morpho...
