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)
"data model algorithm" » "data mould algorithm" (Expand Search), "data models algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element method algorithm\") OR (((\"image processing algorithm\") OR (\"data model algorithm\"))))~".
• Removing quotes may allow a broader search: (( element method algorithm ) OR ((( image processing algorithm ) OR ( data model algorithm ))))~.
• Adding a wildcard symbol may retrieve word variants: (("element method algorithm") OR ((("image processing algorithm") OR ("data model algorithm"))))*.
