Perhaps you should try some spelling variations:
"learning-based 3d segmentation techniques" » "learning-based 3d augmentation techniques", "learning-based 3d imputation techniques", "learning-based _ segmentation techniques", "learning-based co segmentation techniques", "learning-based n segmentation techniques"
"learning-based k inflation technique" » "learning-based k inhalation technique", "learning-based k implantation technique", "learning-based k imputation techniques", "learning-based _ inflation technique", "learning-based n inflation technique", "learning-based co inflation technique"

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 segmentation techniques") or ("learning-based k inflation technique"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("learning-based 3d segmentation techniques") OR ("learning-based k inflation technique")).
• Removing quotes may allow a broader search: (( learning-based 3d segmentation techniques ) or ( learning-based k inflation technique )).
• Adding a wildcard symbol may retrieve word variants: (("learning-based 3d segmentation techniques") or ("learning-based k inflation technique"))*.
