Fuzzy Cluster Method based on RV measure for functional MRI data analysis
Functional magnetic resonance imaging (fMRI) has become one of the important tools of functional connectivity studies of the human brain.Fuzzy clustering method (FCM) is a common method for analysis of fMRI data.Traditional FCA methods measure the similarity between the BOLD time course ofa centroid and the ones of all other voxels in the brain on the basis of Pearson correlation coefficient.This article puts forward a multi-voxel-based RV coefficient similarity measure to overcome the defects of traditional similarity distance measure in FCM.The experimental results show that the RV-based FCA method has not only improved the speed of FCA,but has comparatively raised the accuracy of the method.
