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