Question:SimpleOpenNI, I would want to limit "range of detection".

I am using kinect v1 and SimpleOpenNI.

I would only want to detect person in range of 1m~2m, but kinect would detects and tracks person entire time when the person is its range.

Here, I would want to know method to limit detective range of the kinect .

I would want to limit rage to 2m(width) x 2m(height), 2m(depth).

thank you m(__)m
