Perhaps you should try some spelling variations:
augmentation techniques » imputation techniques
segmentation techniques » imputation techniques
nde segmentation » 3d segmentation, shape segmentation
k augmentation » data augmentation
based nde » based anode, based code, based 3d
based k » based _, based n, based 3d

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

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