Perhaps you should try some spelling variations:
segmentation techniques » augmentation techniques, imputation techniques
floatation technique » inhalation technique, implantation technique, imputation techniques
code segmentation » 3d segmentation, shape segmentation
ko2 floatation » _ floatation
based code » based anode
based ko2 » based no2, based co, based k

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 ko2 floatation technique ) OR ( learning-based code segmentation techniques ))~".
• Adding a wildcard symbol may retrieve word variants: (( learning-based ko2 floatation technique ) OR ( learning-based code segmentation techniques ))*.
