Hi there,

the joint recognition in the new OpenNI version is faster, but got
some real bad behaviours!
Have a look at following picture: http://i.imgur.com/Px1YK.jpg
I got my arms close to my body, but the joints og the arms go in T-
Pose! That would be ok, when the confidence would be set to 0.0f for
those wrong detected joints - but they don't. This behaviour is not as
good as in previous versions.
Also it looks pretty strange, when I go into, or leave the scene! All
joints are completly disorientated, when leaving the scene. When I go
back into it, the hand-joints get in T-pose again, until i move my
arms...

Hope this will be fixed soon.

Hi Michael!

Thanks for the great feedback, we were able to reproduce the same bug
here as well.

It seem to happen when you load/store calibration data and have the
new skeleton heuristics turned on (which are on by default).

We're going to fix it soon but for now you can turn off the new
feature by adding this to your xml file:

<Node type="User">
<Configuration>
<Property type="int" name="SkeletonHeuristics" value="0"/>
</Configuration>
</Node>

Thanks,
Ziv.

Okay, we've fixed the bad joints position problem when loading the
calibration data and we'll fix the bad confidence values very soon
too.

The new version will come out in Sunday after we run all our
regression tests.

Thanks for your help!

Ziv.

Hi Michael!
We just released a new version that fixes that issue... If you have
the time can you possibly test and confirm that it's all good now?
Thanks,
Ziv.
