Hi,
normally I use the opencv stack comming with ros-hydro. But since I need some gpu implementations right now I downloaded 2.4.9 and compiled the sources on my own. I noticed that the performance of my custom build is fa behind the ros stack. FAST_MATH, WITH_EIGEN, WITH_TBB, WITH_CUDA, WITH_CUBLAS was activated, I built the release configuration. Any ideas what optimization is still missing? Also I tried to find the cmake config the ros stack (apt package: ros-hydro-opencv2) is compiled with but didn't find that much despite the jenkins log.
cheers, stfn
