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)
"elements ii algorithm" » "elements _ algorithm" (Expand Search), "elements _ algorithms" (Expand Search), "elements b algorithm" (Expand Search), "elements fe algorithm" (Expand Search)
"element rf algorithm" » "element _ algorithm" (Expand Search), "element art algorithms" (Expand Search), "element new algorithm" (Expand Search), "element ore algorithm" (Expand Search), "element ree 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: (((("elements ii algorithm") OR ("element rf algorithm"))) OR ("image processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements ii algorithm\") OR (\"element rf algorithm\"))) OR (\"image processing algorithm\"))".
• Removing quotes may allow a broader search: (((( elements ii algorithm ) OR ( element rf algorithm ))) OR ( image processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements ii algorithm") OR ("element rf algorithm"))) OR ("image processing algorithm"))*.
