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 based algorithms" » "element based algorithm" (Expand Search), "engagement based algorithms" (Expand Search)
"elements ree algorithms" » "elements tree algorithms" (Expand Search), "elements three algorithms" (Expand Search), "elements rl algorithms" (Expand Search), "element ree algorithms" (Expand Search), "elements res algorithms" (Expand Search), "elements fe 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 ((("elements ree algorithms") OR ("element based algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"image processing algorithm\") OR (((\"elements ree algorithms\") OR (\"element based algorithms\"))))".
• Removing quotes may allow a broader search: (( image processing algorithm ) OR ((( elements ree algorithms ) OR ( element based algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("image processing algorithm") OR ((("elements ree algorithms") OR ("element based algorithms"))))*.
