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 method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"element eii algorithm" » "element ii algorithm" (Expand Search), "element iii algorithm" (Expand Search), "element em algorithm" (Expand Search), "element limit algorithm" (Expand Search), "element mesh 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: (((("element eii algorithm") OR ("element method algorithm"))) OR ("image processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element eii algorithm\") OR (\"element method algorithm\"))) OR (\"image processing algorithm\"))".
• Removing quotes may allow a broader search: (((( element eii algorithm ) OR ( element method algorithm ))) OR ( image processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element eii algorithm") OR ("element method algorithm"))) OR ("image processing algorithm"))*.
