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 rf algorithms" » "element rf algorithm" (Expand Search), "element rl algorithms" (Expand Search), "element art algorithms" (Expand Search), "element ore algorithms" (Expand Search), "element ree algorithms" (Expand Search), "element _ 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 rf algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"image processing algorithm\") OR (((\"element method algorithm\") OR (\"element rf algorithms\"))))".
• Removing quotes may allow a broader search: (( image processing algorithm ) OR ((( element method algorithm ) OR ( element rf algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("image processing algorithm") OR ((("element method algorithm") OR ("element rf algorithms"))))*.
