Perhaps you should try some spelling variations:
"learning-based co segmentation techniques" » "learning-based co augmentation techniques", "learning-based co imputation techniques", "learning-based 3d segmentation techniques", "learning-based code segmentation techniques", "learning-based no2 segmentation techniques", "learning-based two segmentation techniques"
"learning-based codeo2 truncation technique" » "learning-based codeo2 floatation technique", "learning-based codeo2 inhalation technique", "learning-based codeo2 reduction technique", "learning-based code truncation technique", "learning-based codedeo2 truncation technique", "learning-based no2deo2 truncation technique", "learning-based twodeo2 truncation technique"

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 co segmentation techniques\") OR (\"learning-based codeo2 truncation technique\"))~".
• Removing quotes may allow a broader search: (( learning-based co segmentation techniques ) OR ( learning-based codeo2 truncation technique ))~.
• Adding a wildcard symbol may retrieve word variants: (("learning-based co segmentation techniques") OR ("learning-based codeo2 truncation technique"))*.
