Speed of cv::linemod with SSE3

edit

Hi,

I have recently installed Intel IPP and re-build opencv with SSE and IPP. I am trying to run cv::linemod, which is claimed to run at ~120ms for matching 3000 templates.

I have checked that it is making the SSE calls, but still cv::linemod runs at ~4s for ~700 templates. Do you know if the opencv version is able to attain the speed shown in the publication by Hinterstoisser et al. ?
