C# Class Kinect.JointPositionsFilter

Implementation of a Holt Double Exponential Smoothing filter. The double exponential smooths the curve and predicts. There is also noise jitter removal. And maximum prediction bounds. The parameters are commented in the Init function.

Init() public méthode

Initialize the filter with a set of manually specified TransformSmoothParameters.

public Init ( float smoothingValue, float correctionValue, float predictionValue, float jitterRadiusValue, float maxDeviationRadiusValue ) : void
smoothingValue	float	Smoothing = [0..1], lower values is closer to the raw data and more noisy.
correctionValue	float	Correction = [0..1], higher values correct faster and feel more responsive.
predictionValue	float	Prediction = [0..n], how many frames into the future we want to predict.
jitterRadiusValue	float	JitterRadius = The deviation distance in m that defines jitter.
maxDeviationRadiusValue	float	MaxDeviation = The maximum distance in m that filtered positions are allowed to deviate from raw data.
