Hi,

I have got two small webcam logitech c170 and c270. When I run example bgfg_segm.cpp I have got some problems when an object cross the image (my hand). I have made a video : some circle appear I don't think there is automatic adjust gain on this camera. I think that's camera electronics is not good. What do you think ?

thanks for your help

Yes, you are exactly right. This is due to auto gain and auto exposure property of camera. Try disabling AEC and AEC using some camera viewer application like amcap (windows) or cheese (linux) and try experimenting with different manual gain and exposure values suitable for your environment. Eager to see your results:-)
