Perhaps you should try some spelling variations:
segmentation techniques » augmentation techniques, imputation techniques
simulation technique » imputation techniques, inhalation technique, implantation technique
k segmentation » 3d segmentation
3d simulation » _ simulation, a simulation, mri simulation
based 3d » based _, based co, based n
based k » based _, based n, based co

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