im doing circle detection on vdeo feed and i am finding that opencv plays my video back extremely slow. I was wondering if opencv makes use of the graphics card or just the CPU. is there a way to tell opencv to use the graphics card??

OpenCV can be compiled with GPU support using CUDA. Some methods like SURF point extraction have a gpu implementation. See here for more information.
In order to use the GPU support, you need to have CUDA installed and compile the OpenCV source code with the USE_CUDA flag set in CMake.
