Perhaps you should try some spelling variations:
segmentation techniques » augmentation techniques, imputation techniques
reduction techniques » reduction technique, imputation techniques
nde segmentation » 3d segmentation, shape segmentation
no2 reduction » h2o2 reduction, _ reduction
based no2 » based co, based n
based nde » based anode, based code, based 3d

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 no2 reduction techniques ) OR ( learning-based nde segmentation techniques ))~".
• Adding a wildcard symbol may retrieve word variants: (( learning-based no2 reduction techniques ) OR ( learning-based nde segmentation techniques ))*.
