skeleton tracking jitter reduction
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 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
