Perhaps you should try some spelling variations:
"image processing algorithm" » "image processing algorithms" (Expand Search)
"models using algorithm" » "models cosine algorithm" (Expand Search), "model using algorithm" (Expand Search)
"element data algorithm" » "element jaya algorithm" (Expand Search), "element deer algorithm" (Expand Search), "elements 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 ("models using algorithm"))) OR ("element data algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"image processing algorithm\") OR (\"models using algorithm\"))) OR (\"element data algorithm\"))".
• Removing quotes may allow a broader search: (((( image processing algorithm ) OR ( models using algorithm ))) OR ( element data algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("image processing algorithm") OR ("models using algorithm"))) OR ("element data algorithm"))*.
