It has been shown the application of Mean-Shift
Clustering (MSC) to fMRI analysis can increase detection sensitivity in low
contrast to noise situations. In this study, MSC was utilized with a feature
space containing both temporal and spatial features to further increase its
detection power. If successful, the proposed technique can
improve detection in techniques that inherently have low CNR, such as non-proton
fMRI or non-BOLD fMRI.
