Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
pose optimisation » qoe optimization, _ optimisation, pose estimation
counting methods » nursing methods, control methods
code counting » crowd counting
modified pose » modified male, modified passive

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: "(( code counting methods algorithm ) OR ( modified pose optimisation algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( code counting methods algorithm ) OR ( modified pose optimisation algorithm ))*.
