Face Tracking & Recognition Distance Range

[PKusm]

Hi,
I am quite amazed by the performance of RealSense Face Tracking and Recognition algorithm module.
However, as I try to do several experiments, it only works when the face distance in up to 1 meter (approximately).
I have tried to increase it by changing the IVCam properties (Accuracy, Filter Option, and Motion Range) but I have no luck.
Is there anyone who has been successfully track and recognize a face above 1 meter distance away from the camera?

I have just found out that the face recognition distance is ranging from 30 - 80 cm.
I should have read all of the documentation pages thoroughly.
If you guys are looking for this information go check "Algorithm Operating Ranges" subsection on the SDK documentation.
There are also specific distance range for each algorithm provided by RealSense SDK.
Check my attachment for a quick preview.

In my opinion, can not be more than one meter. possible obstacles in the brightness of infrared light and IR camera. but if you can keep the focus point of IR cameras and increase the brightness in infrared light. may be it could be. but this is only my opinion.

I would like to inform that the face recognition can still work above 1m.
I have tested it and tried to recognize a face up to 1.5 m away to the camera.
But of course, we will have to compensate its accuracy and reliability whenever the face is located more distant away from the camera.

Well, in theory you should be able to detect a face that is farther away than 1m by just using the color camera.

You could have a system that has better performance when the face is closer than 1m by adding the 3D information, but still being able to track the head while it is away from the roughly 1m operating distance of the 3D part of the camera.
