Perhaps you should try some spelling variations:
"visual processing algorithm" » "visual processing algorithms" (Expand Search), "signal processing algorithm" (Expand Search)
"image 1_single algorithm" » "image cosine 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: (((("visual processing algorithm") OR ("image 1_single algorithm"))) OR ("element data algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"visual processing algorithm\") OR (\"image 1_single algorithm\"))) OR (\"element data algorithm\"))".
• Removing quotes may allow a broader search: (((( visual processing algorithm ) OR ( image 1_single algorithm ))) OR ( element data algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("visual processing algorithm") OR ("image 1_single algorithm"))) OR ("element data algorithm"))*.
