问题
I am using Emgucv and i would like to know if it possible to remove the background from a _capture.QueryFrame and to be able to focus on the nearest object on my camera? Thanks in advance.

Yes this is quite possible take a look at the "MotionDetection" example provided with EMGU this should get you started.
Effectively the code that removes the foreground is effectively named "_forgroundDetector" it is the "_motionHistory" that presents stores what movement has occurred.
The example has everything you need if you have trouble running it let me know,
