Perhaps you should try some spelling variations:
"image processing algorithm" » "image processing algorithms" (Expand Search)
"element method algorithm" » "element mould algorithm" (Expand Search), "elements method algorithm" (Expand Search)
"trained using algorithm" » "trained cosine algorithm" (Expand Search), "brines using 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 method algorithm") OR ((("image processing algorithm") OR ("trained using algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element method algorithm\") OR (((\"image processing algorithm\") OR (\"trained using algorithm\"))))".
• Removing quotes may allow a broader search: (( element method algorithm ) OR ((( image processing algorithm ) OR ( trained using algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element method algorithm") OR ((("image processing algorithm") OR ("trained using algorithm"))))*.
