Perhaps you should try some spelling variations:
"modified notion estimation algorithms" » "modified notion estimation algorithm", "modified notion optimization algorithms", "modified notion optimisation algorithm", "modified motion estimation algorithms"
"modified pose estimation algorithms" » "modified pose estimation algorithm", "modified pose optimization algorithms", "modified pose optimisation algorithm", "modified male estimation algorithms", "modified passive estimation algorithms"

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 notion estimation algorithms") OR ("modified pose estimation algorithms"))~.
• Removing quotes may allow a broader search: (( modified notion estimation algorithms ) or ( modified pose estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified notion estimation algorithms") or ("modified pose estimation algorithms"))*.
