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)
"relevant data algorithm" » "relevant data algorithms" (Expand Search), "relevant update algorithm" (Expand Search), "relevant atlas algorithm" (Expand Search)
"element de algorithms" » "element mdem algorithms" (Expand Search), "element ml algorithms" (Expand Search), "element _ algorithms" (Expand Search), "element te algorithms" (Expand Search), "elements fe algorithms" (Expand Search), "element fbe 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 ((("relevant data algorithm") OR ("element de algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"image processing algorithm\") OR (((\"relevant data algorithm\") OR (\"element de algorithms\"))))".
• Removing quotes may allow a broader search: (( image processing algorithm ) OR ((( relevant data algorithm ) OR ( element de algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("image processing algorithm") OR ((("relevant data algorithm") OR ("element de algorithms"))))*.
