Perhaps you should try some spelling variations:
"line segment structure analysis" » "line segment structural analysis", "line segmental structure analysis", "line sediment structure analysis", "line pigment structure analysis", "line segments structure analysis"
"line segment texture analysis" » "line segment capture analysis", "line segment text analysis", "line segment failure analysis", "line sediment texture analysis", "line segment feature analysis", "line segment features analysis", "line segments texture analysis"

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: "((\"line segment texture analysis\") OR (\"line segment structure analysis\"))".
• Removing quotes may allow a broader search: (( line segment texture analysis ) OR ( line segment structure analysis )).
• Adding a wildcard symbol may retrieve word variants: (("line segment texture analysis") OR ("line segment structure analysis"))*.
