Abstract

The invention discloses a magnetic resonance image classification method based on an independent component high-order uncertain brain network and relates to the image processing technology. The methodcomprises the steps of extracting a default network independent component by using independent component analysis, then a high-order functional connection network is constructed on the time series ofthe independent component by using a time window sliding method, a frequent subgraph mining and feature selection method based on a weighted graph is used, and the classification and recognition arecarried out with a discriminant subgraph as a feature. The method does not rely on a priori brain atlas template, time-varying characteristics in a scanning time are fully considered, the frequent subgraph mining is applied to the weighted graph, and more advanced and more complex interaction between brain regions is showed. The problem of the low accuracy of a traditional magnetic resonance imagedata classification method is solved.

Description

technical field [0001] The invention belongs to the technical field of image processing, in particular to a magnetic resonance image classification method based on independent component high-order uncertain brain network. Background technique [0002] The human brain is a highly complex system, and exploring its inner structure and function is a great challenge. The combination of functional magnetic resonance imaging technology and complex network theory has become one of the research hotspots in the field of brain science and has been widely used in various researches. This approach has yielded many surprising results in exploring structural and functional interactions between brain regions. However, due to the limitations of its own principles and characteristics and methodology, the classification accuracy is low, which seriously affects the application value. [0003] In recent years, most studies based on brain networks have defined network nodes according to brain m...
