Perhaps you should try some spelling variations:
"image processing algorithm" » "image routing algorithm" (Expand Search), "image tracking algorithm" (Expand Search), "image boosting algorithm" (Expand Search)
"image modeling algorithm" » "image making algorithm" (Expand Search), "age modeling algorithm" (Expand Search), "climate modeling algorithm" (Expand Search), "case modeling algorithm" (Expand Search)
"relevant data algorithm" » "relevant data algorithms" (Expand Search), "relevant update algorithm" (Expand Search), "relevant 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: (((("image processing algorithm") OR ("image modeling algorithm"))) OR ("relevant data algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"image processing algorithm\") OR (\"image modeling algorithm\"))) OR (\"relevant data algorithm\"))".
• Removing quotes may allow a broader search: (((( image processing algorithm ) OR ( image modeling algorithm ))) OR ( relevant data algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("image processing algorithm") OR ("image modeling algorithm"))) OR ("relevant data algorithm"))*.
