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