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 method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"element mesh algorithms" » "element best algorithms" (Expand Search), "element ml algorithms" (Expand Search), "element best algorithm" (Expand Search), "elements mges algorithms" (Expand Search), "element te algorithms" (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: (("image processing algorithm") OR ((("element method algorithm") OR ("element mesh algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"image processing algorithm\") OR (((\"element method algorithm\") OR (\"element mesh algorithms\"))))".
• Removing quotes may allow a broader search: (( image processing algorithm ) OR ((( element method algorithm ) OR ( element mesh algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("image processing algorithm") OR ((("element method algorithm") OR ("element mesh algorithms"))))*.
