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)
"fold processing algorithm" » "fold modeling algorithm" (Expand Search), "fold routing algorithm" (Expand Search), "fold tracking algorithm" (Expand Search), "food processing algorithm" (Expand Search), "wood processing algorithm" (Expand Search), "post processing algorithm" (Expand Search)
"present data algorithm" » "present data algorithms" (Expand Search), "present update algorithm" (Expand Search), "present atlas algorithm" (Expand Search), "presence data algorithm" (Expand Search), "present day algorithm" (Expand Search), "recent data 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 ("fold processing algorithm"))) OR ("present data algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"image processing algorithm\") OR (\"fold processing algorithm\"))) OR (\"present data algorithm\"))".
• Removing quotes may allow a broader search: (((( image processing algorithm ) OR ( fold processing algorithm ))) OR ( present data algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("image processing algorithm") OR ("fold processing algorithm"))) OR ("present data algorithm"))*.
