Perhaps you should try some spelling variations:
functions segmentation » motion segmentation, detection segmentation, functions computation
region segmentation » motion segmentation, brain segmentation, skin segmentation
method discursive » methods dispersive, methods discourse
discursive based » discourse based, discussion based, discipline based
based active » based adaptive

You may be able to get more results by adjusting your search query.

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