Perhaps you should try some spelling variations:
"image processing algorithm" » "image modeling algorithm" (Expand Search), "image routing algorithm" (Expand Search), "image tracking algorithm" (Expand Search)
"element based algorithms" » "element based algorithm" (Expand Search), "engagement based algorithms" (Expand Search)
"element mesh algorithm" » "element best algorithm" (Expand Search), "element mean algorithm" (Expand Search), "element means algorithm" (Expand Search), "element method algorithm" (Expand Search), "elements mges algorithm" (Expand Search), "element te algorithm" (Expand Search)

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("element mesh algorithm") OR ("element based algorithms"))) OR ("image processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element mesh algorithm\") OR (\"element based algorithms\"))) OR (\"image processing algorithm\"))".
• Removing quotes may allow a broader search: (((( element mesh algorithm ) OR ( element based algorithms ))) OR ( image processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element mesh algorithm") OR ("element based algorithms"))) OR ("image processing algorithm"))*.
