Perhaps you should try some spelling variations:
"modified objective convolution algorithms" » "modified objective evolution algorithm", "modified objective solution algorithm"
"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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective convolution algorithms\") OR (\"modified pose estimation algorithms\"))~".
• Removing quotes may allow a broader search: (( modified objective convolution algorithms ) OR ( modified pose estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective convolution algorithms") OR ("modified pose estimation algorithms"))*.
