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