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 anbs algorithm" » "element means algorithm" (Expand Search), "element new algorithm" (Expand Search), "element cnn algorithm" (Expand Search), "element fbe algorithm" (Expand Search)
"element tide algorithm" » "element td3 algorithm" (Expand Search), "element leiden algorithm" (Expand Search), "element five algorithms" (Expand Search), "element te algorithm" (Expand Search), "element model algorithm" (Expand Search), "element study 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 anbs algorithm") OR ("element tide algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"image processing algorithm\") OR (((\"element anbs algorithm\") OR (\"element tide algorithm\"))))".
• Removing quotes may allow a broader search: (( image processing algorithm ) OR ((( element anbs algorithm ) OR ( element tide algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("image processing algorithm") OR ((("element anbs algorithm") OR ("element tide algorithm"))))*.
