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