Does anyone have any advice on ways to improve the stability of joint tracking when using the MS sdk kinect plugins? I’m trying to achieve smooth as possible hand tracking for a gesture interface.
Any combination of filters that people have used successfully would be great to know, as would settings for the SmoothSettings node (Is there any documentation for this?)
I’m currently having a play with Kalle’s Transient module btw
// Smoothed with some latency.
// Filters out medium jitters.
// Good for a menu system that needs to be smooth but
// doesn’t need the reduced latency as much as gesture recognition does.
const NUI_TRANSFORM_SMOOTH_PARAMETERS SomewhatLatentParams =
{0.5f, 0.1f, 0.5f, 0.1f, 0.1f};
slight damping proportional to joint speed (this is great)
further damping of any inferred joints (rather than tracked)
I’ll try to share a patch soon, though the settings I’m using are heavily biased towards this particular application. It would be nice after some more experimentation to make a general purpose module with some presets for different applications
edit - does anyone think a weighted moving average filter might be more effective than a damper for any of these steps?
