skeleton tracking jitter reduction

edited October 2014 in Kinect

Hi Can somebody know how to minimize the jitter during the skeleton tracking ? I`m developing in fall detection system using skeletal tracking. I want to calculate the angle between some selected joints. I know it has a drawbacks when detecting person is not in upright position. but i want to minimize the jitter.

Any suggestion to development ??


  • simplest solution that comes to my mind is computing averages of the let's say last 10 values. maybe giving the newer values a higher weight then the older values.

  • can u explain it bit more please..

    check this

    "A moving average is commonly used with time series data to smooth out short-term fluctuations and highlight longer-term trends or cycles"

    most simple moving average would be to add up the last ten angles and divide it by ten. (angle1 + angle2 + ... + angle10) / 10
