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