Perhaps you should try some spelling variations:
"visual processing algorithm" » "visual processing algorithms" (Expand Search), "signal processing algorithm" (Expand Search)
"image 2_using algorithm" » "image cosine algorithm" (Expand Search)
"relevant data algorithm" » "relevant jaya algorithm" (Expand Search), "relevant deer 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 2_using algorithm") OR ("visual processing algorithm"))) OR ("relevant data algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"image 2_using algorithm\") OR (\"visual processing algorithm\"))) OR (\"relevant data algorithm\"))".
• Removing quotes may allow a broader search: (((( image 2_using algorithm ) OR ( visual processing algorithm ))) OR ( relevant data algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("image 2_using algorithm") OR ("visual processing algorithm"))) OR ("relevant data algorithm"))*.
