Perhaps you should try some spelling variations:
"learning-based 3D augmentation techniques" » "learning-based 3D segmentation techniques"
"learning-based 3D imputation techniques" » "learning-based 3D implantation technique", "learning-based 3D segmentation techniques", "learning-based 3D floatation technique"
3d augmentation » 3d segmentation, data augmentation
3d imputation » 3d simulation
based 3d » based _, based co, based k

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("learning-based 3D augmentation techniques") OR ("learning-based 3D imputation techniques"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"learning-based 3D augmentation techniques\") OR (\"learning-based 3D imputation techniques\"))*".
• Removing quotes may allow a broader search: (( learning-based 3D augmentation techniques ) OR ( learning-based 3D imputation techniques ))*.
