Smoothing Skeleton Data (custom), Pre-Processing

Question

Hi

I am just wondering if anyone knows any methods that can be researched on-line and/or any tutorial on smoothing skeletal data before serialization of the joint data? In the sense of custom algorithms or predictive algorithms.

I have already used the TransformSmoothParameters class which has helped to a degree but still not good enough.

With the project i am doing there is no importance of speed of processing and it does not matter if it lags a lot, it is not for use in a game.

I have been able to implement some post-processing to correct the data mathematically but for accuracy reasons i would like to minimise the amount of errors at input.

Apologies if this is a bit of a simple question but I'm normally a UI type, this is fairly scientific for me!

Regards,

David 

Answer 1

Why not just switch off the smoothing parameters, and then apply your algorithms?  The joint locations are determined using a decision tree based on a per-pixel analysis of the depth data, so there probably isn't much you can do prior to the raw joints produced without smoothing.
