The number of frames depend on the movement you recorded and the
sampling frequency.

Some orks usely used a moving average of 5 frames, does it help ?

Subject: [BIOMCH-L] data interpolation

Dear all

I am collecting some kinematic data of the feet during walking; my
colleague is collecting reaching data. Both of us are wondering, if we
have missing data, over how many frames would it be considered
acceptable to interpolate the data? We are using the linear
interpolation and spline functions in Matlab.

Many thanks
