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)
"movement data algorithm" » "movement data algorithms" (Expand Search), "movement update algorithm" (Expand Search), "movement atlas 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 based algorithm") OR ("movement data algorithm"))) OR ("image processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements based algorithm\") OR (\"movement data algorithm\"))) OR (\"image processing algorithm\"))".
• Removing quotes may allow a broader search: (((( elements based algorithm ) OR ( movement data algorithm ))) OR ( image processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements based algorithm") OR ("movement data algorithm"))) OR ("image processing algorithm"))*.
