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)
"present study algorithm" » "present wsindy algorithm" (Expand Search), "present td3 algorithm" (Expand Search), "present seu algorithm" (Expand Search)
"element ore algorithms" » "element tree algorithms" (Expand Search), "element art algorithms" (Expand Search), "element rl algorithms" (Expand Search), "element te algorithms" (Expand Search), "element fbe algorithms" (Expand Search), "element ree algorithms" (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: (((("present study algorithm") OR ("element ore algorithms"))) OR ("image processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"present study algorithm\") OR (\"element ore algorithms\"))) OR (\"image processing algorithm\"))".
• Removing quotes may allow a broader search: (((( present study algorithm ) OR ( element ore algorithms ))) OR ( image processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("present study algorithm") OR ("element ore algorithms"))) OR ("image processing algorithm"))*.
