Service Hospitalier Frederic Joliot, CEA, Orsay, France
IEEE Trans Med Imaging 21:470-84. 2002..Some more work, however, is required to compare the various robust metrics proposed in the literature...
- Motion correction algorithms may create spurious brain activations in the absence of subject motionL Freire
, CEA, 91401 Orsay, France
Neuroimage 14:709-22. 2001..All the experiments are performed using four different realignment methods, which allows us to show that the problem may be overcome by methods based on a robust similarity measure like mutual information...
