Kinect user bones orientation data

Hi Guys, I am working a kinect project and I am beginner in kinect.
I need to match the players current bones orientation with an image (predefined bones orientation).
Can anybody guide?
I have found bonesPos vector array but it seems quite complex…

I found some answer…we can access the bones orientation using SkeletonWrapper class…
e.g. SkeletonWrapper sw; //Assign Kinect Prefab from the inspector

using UnityEngine;
using System.Collections;

public class PrintBonesPos : MonoBehaviour {
private Kinect.KinectInterface kinect;

private Matrix4x4 kinectToWorld;

public SkeletonWrapper sw;


Vector3[] poseMin;

Vector3[] poseMax;

// Use this for initialization
void Start () {


	
}

// Update is called once per frame
void Update () {
	for(int bone = 0;bone < (int)Kinect.NuiSkeletonPositionIndex.Count; bone++)
	{
		print("Bone pos for "+bone+" is "+sw.bonePos[0,bone]); //= kinectToWorld.MultiplyPoint3x4(kinect.getSkeleton().SkeletonData[0].SkeletonPositions[bone]);
		
	}
	
	
}

}
