Perhaps you should try some spelling variations:
imagem processing » image processing (Expand search), images processing (Expand search), imaging processing (Expand search)
decrease imagem » decrease age (Expand search)
that decrease » that increase (Expand search), that increases (Expand search), not decrease (Expand search)
decrease the » decreases the (Expand search), decrease in (Expand search), decrease of (Expand search)
the decrease » to decrease (Expand search), and decrease (Expand search)
decrease may » decrease at (Expand search), decrease by (Expand search), decrease human (Expand search)
may decrease » may increase (Expand search), can decrease (Expand search), to decrease (Expand search)
decree that » decrees that (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: "(( decree that decrease the decrease ) OR ( decrease may decrease imagem processing ))~".
• Adding a wildcard symbol may retrieve word variants: (( decree that decrease the decrease ) OR ( decrease may decrease imagem processing ))*.
