Robust Brain ROI Segmentation by Deformation Regression and Deformable Shape Model

Human brain function network is characterized by the functional connectivity of different brain regions (Li et  al., 2009; Tzourio-Mazoyer et al., 2002; Fischl et al., 2002). The functional connectivity can be quantified as a connectivity matrix, where each entry measures the Pearson or partial correlation between the functional activities of two brain regions of interest (ROIs) (Liu et al., 2012; Liu an d Ye, 2010). To calculate the connectivity matrix, the brain ROIs need to be segmented from MR images.
