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