2013-04-09 14:10:44 -0600	asked a question	BackgroundSubtractor::getBackgroundImage in pure C Hi, guys! I'm a bit confused with algos using in pure C. I didn't find C-interfaces for BackgroundSubtractor(MOG)::getBackgroundImage. How should one use it properly? I suspect, it must be implemented by myself if I want to use pure C? Are there some short examples in C? Thanks!

2012-08-21 04:59:55 -0600	asked a question	Huge time to upload data to GPU Good day! I've just built the latest master branch of OpenCV with CUDA support. So, I tried some sample code: Mat shot = imread("D:\\shot.bmp"); // Shot.bmp is a picture 1571x1002 gpu::GpuMat gpuShot; gpuShot.upload(shot); The last line "gpuShot.upload(shot);" takes huge time to invoke! It takes about 4-5 seconds to upload to GPU! Is it normal for that? I don't think so... BTW: My hardware is GeForce GT 520. And second question: the file "opencv_gpu249d.dll" has size about 250 Mb! Meanwhile, "opencv_gpu242d.dll" from official prebuild boundle (v.2.4.2) has size approx 800 Kb. What the hell of a size? And what I doing wrong? Please help, thanks.
