Post subject:  Discarding background by only RGB color(Azure Kinect)?

Hello everyone,
Does IpiRecorder discard background by ONLY RGB color instead of depth channel when using Azure Kinect ?
It seemed that the background remained if I take my video without recording the RGB color channel. I can’t discard it.

Is the principle of background removal is the same as that when I was using regular RGB Cameras ?

I am really confused. I need your reply very much. Many Thanks.

No, background is evaluated both for color and depth data. If you see the background with "Hide Background" option then a camera has probably moved since background evaluation.

I'm sorry for my expression ability.But this is not the point of my question.

The most important point is if I discard the RGB data , will I get the exactly same result of background removal when all the cameras do not move a bit?

Thank you very much.

Background processing is independent for depth and RGB, so you'll get the same background removal for depth whether you do or don't record RGB.
