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)
"image using algorithms" » "image pacing algorithms" (Expand Search), "image nine algorithms" (Expand Search), "image sorting algorithms" (Expand Search), "images using algorithms" (Expand Search), "made using algorithms" (Expand Search), "imaging using algorithms" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean 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: (((("image processing algorithm") OR ("image using algorithms"))) OR ("element method algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"image processing algorithm\") OR (\"image using algorithms\"))) OR (\"element method algorithm\"))".
• Removing quotes may allow a broader search: (((( image processing algorithm ) OR ( image using algorithms ))) OR ( element method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("image processing algorithm") OR ("image using algorithms"))) OR ("element method algorithm"))*.
