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