Hi Everyone,

I'm new to Open CV and present working on my project which needs background separation done with OpenCV.

Two days back I configured Open CV with Visual Studio C++ 2010 and worked on small tutorials from this blog http://opencv-srf.blogspot.ie/

By I am not sure about how to make the BGS from a video file and background image I am having on my disk...

Can anyone please suggest me with some code that could help me in extracting the background from video (type: quick time movie)by using static background image (jpeg).

Thanks in anticipation

Kindest Regards,

Vijay Kakani

May be I do not fully understand your question, but what does mean "using static background image"? If your already have it, why you need to separate it?

Hi Victor1234, Firstly, thanks for your prompt response. I have a jpeg picture (one static frame of video clip), can I use that static picture to separate the background in the whole video clip (quick time movie {.mov} )??? Sorry for not conveying the question properly

If you have a picture of your scene, without any object of interest, you could just do a simple thresholding (absdiff). The results will depend on your scene, and if there is illumination change (almost the case instead you are using a control light).

If you could take more than just an image, look at the background subtraction of OpenCV BackgroundSubtractor or VIBE. You could also look at the sample bgfg_segm.cpp and bgfg_gmg.cpp in OpenCV/samples/cpp.
