Optimal parameter for the gesture recognition with RealSense

Hi all,

I am testing Nuitrack gesture recognizer with RealSense using nuitrack_gl_sample program.
I am using D415 cams, but the quality of recognition is not fine. (better than D435 maybe…)

So, I adjusted the parameter of Realsense2Module section on nuitrack.config.
At first, I changed the resolution from 640x480 to 1280x720, the quality of skeletal tracking becomes better, but gesture was not enough.
RealSense Viewer App has preseted configurations, such as Default, Hand, High Accuracy, can I accept this parameters for Nuitrack SDK ?

Additional question, Nuitrack SDK uses RGB image for gesture recognizer ? We may use SDK without RGB images.

Best regards.
