Perhaps you should try some spelling variations:
"image processing algorithm" » "image processing algorithms" (Expand Search)
"case making algorithm" » "case cosine algorithm" (Expand Search), "lane marking algorithm" (Expand Search)
"element method algorithm" » "element mould algorithm" (Expand Search), "elements method 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: "((((\"image processing algorithm\") OR (\"case making algorithm\"))) OR (\"element method algorithm\"))~".
• Removing quotes may allow a broader search: (((( image processing algorithm ) OR ( case making algorithm ))) OR ( element method algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("image processing algorithm") OR ("case making algorithm"))) OR ("element method algorithm"))*.
