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.

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 http://en.wikipedia.org/wiki/Moving_average
"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
