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 tree algorithms" » "element three algorithms" (Expand Search), "element art algorithms" (Expand Search), "element two algorithms" (Expand Search), "element ree algorithms" (Expand Search), "element te algorithms" (Expand Search), "element ore algorithms" (Expand Search)
"elements tem algorithms" » "elements mdem algorithms" (Expand Search), "elements mcem algorithms" (Expand Search), "elements two algorithms" (Expand Search), "element te algorithms" (Expand Search), "elements fe algorithms" (Expand Search), "elements ppm 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 tem algorithms") OR ("element tree algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"image processing algorithm\") OR (((\"elements tem algorithms\") OR (\"element tree algorithms\"))))".
• Removing quotes may allow a broader search: (( image processing algorithm ) OR ((( elements tem algorithms ) OR ( element tree algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("image processing algorithm") OR ((("elements tem algorithms") OR ("element tree algorithms"))))*.
