Perhaps you should try some spelling variations:
estimation algorithmss » estimation algorithm, optimization algorithms
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
qoe estimation » _ estimation, cover estimations, qoe optimization
modified pose » modified male, modified passive
modified qoe » modified male, modified _, modified bi1

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: (( modified pose estimation algorithmss ) OR ( modified qoe estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified pose estimation algorithmss ) or ( modified qoe estimation algorithms ))*.
