Perhaps you should try some spelling variations:
segmentation techniques » augmentation techniques, imputation techniques
implantation technique » imputation techniques, floatation technique, inhalation technique
anode implantation » novel implantation
n segmentation » 3d segmentation
based anode » based code
based n » based _, based k, based no2

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