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: "((((\"image processing algorithm\") OR (\"data model algorithm\"))) OR (\"element method algorithm\"))~".
• Removing quotes may allow a broader search: (((( image processing algorithm ) OR ( data model algorithm ))) OR ( element method algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("image processing algorithm") OR ("data model algorithm"))) OR ("element method algorithm"))*.
