Perhaps you should try some spelling variations:
the preprocessing » the processing (Expand search), their processing (Expand search), image preprocessing (Expand search)
foods decreases » loss decreases (Expand search)
decrease cells » decrease cell (Expand search), decreases cell (Expand search), decrease costs (Expand search)
cells decrease » cells decreases (Expand search), cells increase (Expand search), cells increases (Expand search)
decrease foods » decrease food (Expand search), decreases food (Expand search), decreased food (Expand search)
decrease the » decreases the (Expand search), decrease in (Expand search), decrease of (Expand search)
decrease and » decreases and (Expand search), decrease in (Expand search), decrease of (Expand search)
and decrease » and decreases (Expand search), and decreased (Expand search), and increase (Expand search)

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( decrease cells decrease the preprocessing ) OR ( decrease AND decrease foods decreases ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease cells decrease the preprocessing ) OR ( decrease and decrease foods decreases ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease cells decrease the preprocessing ) OR ( decrease and decrease foods decreases ))*.
