Perhaps you should try some spelling variations:
segmentation techniques » imputation techniques
augmentation techniques » imputation techniques
tool augmentation » data augmentation, tool orientation
n segmentation » 3d segmentation
based tool » based two
based n » based _, based k, based no2

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: "(( learning-based n segmentation techniques ) OR ( learning-based tool augmentation techniques ))~".
• Adding a wildcard symbol may retrieve word variants: (( learning-based n segmentation techniques ) OR ( learning-based tool augmentation techniques ))*.
