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 algorithms" » "elements based algorithm" (Expand Search), "experiments based algorithms" (Expand Search), "elements related algorithms" (Expand Search)
"element te algorithms" » "element de algorithms" (Expand Search), "element tree algorithms" (Expand Search), "element two algorithms" (Expand Search), "element _ algorithms" (Expand Search), "element g algorithms" (Expand Search), "element data algorithms" (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 ((("element te algorithms") OR ("elements based algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"image processing algorithm\") OR (((\"element te algorithms\") OR (\"elements based algorithms\"))))".
• Removing quotes may allow a broader search: (( image processing algorithm ) OR ((( element te algorithms ) OR ( elements based algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("image processing algorithm") OR ((("element te algorithms") OR ("elements based algorithms"))))*.
