Perhaps you should try some spelling variations:
"modified pose estimation algorithms" » "modified pose estimation algorithm", "modified pose optimization algorithms", "modified pose optimisation algorithm", "modified male estimation algorithms", "modified passive estimation algorithms"
"modified learning convolution algorithm" » "modified learning convolution algorithms", "modified learning evolution algorithm", "modified learning solution algorithm", "mobile learning convolution algorithm", "modified caging convolution algorithm"

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