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