function computation » function computing, function decomposition, section computational
region segmentation » motion segmentation, brain segmentation, skin segmentation
method discursive » methods dispersive, methods discourse
discursive based » discourse based, discussion based, discipline based

• The words AND, OR and NOT may confuse the search; try adding quotes: "((function computation) OR (region segmentation)) method discursive based ad".
• Adding a wildcard symbol may retrieve word variants: ((function computation) OR (region segmentation)) method discursive based ad*.
