Perhaps you should try some spelling variations:
require optimization » required optimization (Expand Search), resource optimization (Expand Search), feature optimization (Expand Search)
driven optimization » design optimization (Expand Search), guided optimization (Expand Search), dose optimization (Expand Search)
mask require » may require (Expand Search), also require (Expand Search)
binary mask » binary image (Expand Search)
binary mapk » binary image (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: "(( binary mask require optimization algorithm ) OR ( binary mapk driven optimization algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( binary mask require optimization algorithm ) OR ( binary mapk driven optimization algorithm ))*.
