Perhaps you should try some spelling variations:
segmentation techniques » augmentation techniques, imputation techniques
section techniques » reduction techniques, reduction technique, vision techniques
no2 segmentation » 3d segmentation
closed section » closed reduction, cross section
based closed » based code, based cross
based no2 » based co, based n

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 no2 segmentation techniques ) or ( learning-based closed section techniques ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( learning-based no2 segmentation techniques ) OR ( learning-based closed section techniques )).
• Adding a wildcard symbol may retrieve word variants: (( learning-based no2 segmentation techniques ) or ( learning-based closed section techniques ))*.
