Perhaps you should try some spelling variations:
"image matching algorithm" » "image making algorithm" (Expand Search), "image modeling algorithm" (Expand Search), "image mining algorithm" (Expand Search), "case matching algorithm" (Expand Search), "phase matching algorithm" (Expand Search), "scale matching algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"element cscap algorithm" » "element cc3d algorithm" (Expand Search), "element ipca algorithm" (Expand Search), "element custom 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 matching algorithm") OR ((("element cscap algorithm") OR ("element method algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"image matching algorithm\") OR (((\"element cscap algorithm\") OR (\"element method algorithm\"))))".
• Removing quotes may allow a broader search: (( image matching algorithm ) OR ((( element cscap algorithm ) OR ( element method algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("image matching algorithm") OR ((("element cscap algorithm") OR ("element method algorithm"))))*.
