Table 2.

Total sequences investigated in this work along with the training and testing dice scores. Sequence-1 to sequence-8 performed on BraTS-2018 while sequence-9 and sequence-10 performed over BaTS-2015 an BraTS-2013, respectively. * shows that this technique was employed as pre-processing technique prior to the Gibbs ringing artifact removal technique.
