Abstract

THROUGHOUT THE LAST DECADE, FUNCTIONAL MAGNETIC RESONANCE IMAGING (FMRI) MERGED TO A NOTICEABLE TOOL FOR INVESTIGATING THE FUNCTIONAL ANATOMY OF THE HUMAN BRAIN, AND A PLENTY OF ANALYSIS METHODS WERE DEVELOPED FOR ANALYSIS OF ITS DATA. THE ANALYSIS METHODS NEED TO BE COMPARED AND EVALUATED IN A SYSTEMATIC APPROACH. IN THIS PAPER, A CLUSTER-BASED FRAMEWORK IS INTRODUCED FOR COMPARING ANALYSIS METHODS OF FMRI IMAGES.IN THE PROPOSED FRAMEWORK, FMRI DATA IS REPLACED WITH A FEATURE SPACE AND EACH METHOD IS TREATED AS A CLUSTERING METHOD IN THE NEW SPACE. AS A RESULT, DIFFERENT METHODS CAN BE COMPARED BY MEANS OF A CLUSTER VALIDITY MEASURE. THE FEATURE SPACE IS COMPUTED USING A NON-PARAMETRIC METHOD (PRINCIPAL COMPONENT ANALYSIS-PCA). FOUR SUBJECTS HAVE BEEN ANALYZED WITH THREE METHODS (CORRELATION ANALYSIS, F TEST METHOD, AND TIME INVARIANT WAVELET-BASED METHOD) AND THE PROPOSED CLUSTER-BASED FRAMEWORK HAS EVALUATED PERFORMANCE OF THE METHODS. THE RESULTS ARE IDENTICAL TO THOSE OF THE MODIFIED RECEIVER OPERATING CHARACTERISTICS (ROC). THIS VALIDATES THE PROPOSED APPROACH.
