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

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( learning-based n segmentation techniques ) OR ( learning-based nde imputation techniques ))".
• Adding a wildcard symbol may retrieve word variants: (( learning-based n segmentation techniques ) OR ( learning-based nde imputation techniques ))*.
