Hi all, I'm a student. I've never used before Alglib and I need an help.
I'm working on a project for gesture recognition, this is my application's video:

I'm using DTW (dynamic time warping) for recognition, but this is very slow.
I have ten sequence of movements (example, Hand Left on, Hand right on, ecc.)
I post here an example of my data:

<?xml version="1.0" encoding="utf-8"?>
<!--Questo file contiene le sequenze regitrate dal Kinect.-->
<Sequence ID_sequence="10">
<Observation ID_observation="0">
<Joint joint_element="Head">
<X>-0,0681642160598825</X>
<Y>-0,829331295395237</Y>
</Joint>
<Joint joint_element="HandLeft">
<X>-0,704363565952119</X>
<Y>1,60185907740724</Y>
</Joint>
<Joint joint_element="HandRight">
<X>0,681642160598825</X>
<Y>1,67002329346712</Y>
</Joint>
<Joint joint_element="Spine">
<X>0</X>
<Y>0,727084971305413</Y>
</Joint>
<Joint joint_element="FootLeft">
<X>-0,261296161562883</X>
<Y>3,73767118061689</Y>
</Joint>
<Joint joint_element="FootRight">
<X>0,261296161562883</X>
<Y>3,70358907258695</Y>
</Joint>
</Observation>
<Observation ID_observation="1">
.......

I can also obtain data of distance or angles between the body joints.

I work with positive and negative numbers (double) .
Can I create a Decision forest with AlgLib for these value?
Can you give me an advice or link for see an example for use of Alglib in c#?

Thanks you very much
