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)
"recent study algorithm" » "recent wsindy algorithm" (Expand Search), "recent td3 algorithm" (Expand Search), "recent seu algorithm" (Expand Search), "present study algorithm" (Expand Search), "recent studies 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 ((("present data algorithm") OR ("recent study algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"image processing algorithm\") OR (((\"present data algorithm\") OR (\"recent study algorithm\"))))".
• Removing quotes may allow a broader search: (( image processing algorithm ) OR ((( present data algorithm ) OR ( recent study algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("image processing algorithm") OR ((("present data algorithm") OR ("recent study algorithm"))))*.
