How to Apply Smooths Frame Display Using TransformSmoothParameters

In my previous posts about Kinect, I talked about getting started with Kinect SDK from Kinect .NET SDK–Getting Started, Kinect – Getting Started – Control Camera Angle and Kinect – Getting Started – Become The Incredible Hulk.

Kinect SDK has a lot to offer and now I’m going to talk about how to improve Kinect movement by applying TransformSmoothParameters.

The Kinect Nui SDK allow you to apply TransformSmooth just by calling the SkeletonEngine and set it to true:

C#
_kinectNui.SkeletonEngine.TransformSmooth = true;

But this is not enough because you need to define how smooth it’s doing to be, for that we going to use the TransformSmoothParameters.

C#
namespace Microsoft.Research.Kinect.Nui
{     
	[StructLayout(LayoutKind.Sequential, Pack = 8, Size = 24)]     
	public struct TransformSmoothParameters     
	{         
		public float Smoothing { get; set; }         
		public float Correction { get; set; }         
		public float Prediction { get; set; }         
		public float JitterRadius { get; set; }         
		public float MaxDeviationRadius { get; set; }     
	}
}

Here is an example:

C#
var parameters = new TransformSmoothParameters
{     
	Smoothing = 1.0f,     
	Correction = 0.1f,     
	Prediction = 0.1f,     
	JitterRadius = 0.05f,     
	MaxDeviationRadius = 0.05f
};
_kinectNui.SkeletonEngine.SmoothParameters = parameters;

Applying TransformSmoothParameters parameters will improve Kinect movement, you will be able to see the pointer isn’t jumping from place to place.
