Perhaps you should try some spelling variations:
"image processing algorithm" » "image modeling algorithm" (Expand Search), "image routing algorithm" (Expand Search), "image tracking algorithm" (Expand Search)
"element ipca algorithm" » "element wgcna algorithm" (Expand Search), "element cscap algorithm" (Expand Search), "element ii algorithm" (Expand Search), "element data algorithm" (Expand Search)
"element em algorithm" » "element new algorithm" (Expand Search), "element _ algorithm" (Expand Search), "element ii algorithm" (Expand Search), "element ree algorithm" (Expand Search), "element g 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: (((("element ipca algorithm") OR ("element em algorithm"))) OR ("image processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element ipca algorithm\") OR (\"element em algorithm\"))) OR (\"image processing algorithm\"))".
• Removing quotes may allow a broader search: (((( element ipca algorithm ) OR ( element em algorithm ))) OR ( image processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element ipca algorithm") OR ("element em algorithm"))) OR ("image processing algorithm"))*.
