Perhaps you should try some spelling variations:
"image processing algorithm" » "image processing algorithms" (Expand Search)
"element method algorithm" » "element mould algorithm" (Expand Search), "elements method algorithm" (Expand Search)
"case making algorithm" » "case cosine algorithm" (Expand Search), "lane marking algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element method algorithm\") OR (((\"image processing algorithm\") OR (\"case making algorithm\"))))~".
• Removing quotes may allow a broader search: (( element method algorithm ) OR ((( image processing algorithm ) OR ( case making algorithm ))))~.
• Adding a wildcard symbol may retrieve word variants: (("element method algorithm") OR ((("image processing algorithm") OR ("case making algorithm"))))*.
