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

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: "(( cover estimations algorithm ) OR ( qoe estimation algorithms ))~".
• Adding a wildcard symbol may retrieve word variants: (( cover estimations algorithm ) OR ( qoe estimation algorithms ))*.
