Kinect for background subtraction
-
I am working on a little processing app who send by syphon the color image and the mask for the background. I will publish it soon, works on mac with V2
-
Jaques, by v2 you mean the Kinect one?
-
Armando,
Yes the Kinect One is named V2 by the super-geeks…Salute -
@jhoepffner , thanks for your post. It would be amazing if you could let us know when you're ready with the app.
-
@Dusx, I'm working on a mac. Thanks anyway.

Hello,
I can post the actual state of app.
Inside the .zip, you have the folder containing the processing project (too heavy to make an app…), you need:
– Processing 2 or 3– last syphon library (Processing website)
– last OscP5 library (")
– last Open Kinect For Processing library (")
You need to install some libraries on your computer (see here http://shiffman.net/p5/kinect/)
There is also a Isadora patch, to receive depth image and RGB image, adjust the settings for depth and a scene with sample of alpha masking.
Quite rough but it works, for me on MacOs 10.10 with Isadora 2.5, Processing 3 and kinect V2 (kinect One with windows link). It can works with V1 if you modify some parameters.
Fell free to give me feedback.

@jhoepffner thanks for sharing this,
it works! great work.I am trying to see whether it's possible to work directly with the registered image, to avoid bringing out two separate syphon instances. I can send the image through, but can't seem to work on the threshold of the depth data. Also, on the registered image the depth pixels are slightly off and not sure how to fix it. -
-
Or perhaps, use a blend more directly in processing, I've tried it but can't seem to make it work. Sorry, really new to processing, so haven't figured out the logic yet.
thanks! -
If anyone would like to try/test this
https://github.com/rwebber/kinect2sharePlease do and let me know how it goes. -
Thanks Ryan. I am going to ask the dumb question here, but when I download something from github it comes a zip. When I unzip it its always just lots of files and code like documents. Am I doing something wrong; or should this be an application ".app" ?
-
The 'release' zip has the app 'exe'. This is windows only.
The izzy sample file is in the code files... I need to update that... i forgot to add it to the release. -
Thats ok. Just wanted to check.

Hi there,
do you know if there is an alternative for MAC to Daniel Shiffman's library in processing?While testing the file [@jhoepffner](http://troikatronix.com/troikatronixforum/profile/jhoepffner) I got an error, processing cannot find the device (kinect v.2).It seems like mac and kinect v.2 are not working well.Any suggestions how to solve this?Thanks -

Hello,
I you follow the procedure of libraries install (as described in Shiffman post, mainly freenect), it will work well.some things to note– you need a USB3 connection– sometime you need to unplug/replug the kinect– kinect V2 on mac gives you rawDeep info, color image, IR image but no skeleton infos.I used it on a an installation one month ago, Processing to Isadora to Processing, no problem.https://vimeo.com/194632092I do not know of other working kinect Processing library on mac.Millumin is able to have skeleton infos on mac but no way to output the info to Isadora…Hope that helps -
I have made a few updates to this app:
https://github.com/rwebber/kinect2share
It now outputs the Hand state (is the right or left hand open or closed) as well as a number of other small things.The black and white mask (silhouette) is available via spout by default, as well, the 'green screen' type feed is there, incase you want live background subtraction. -
@jhoepffner the problem I got with Shiffman's library does happen, I don't know why and how, this has developed into an unsolvable mystery.
https://github.com/shiffman/OpenKinect-for-Processing/issues/80A couple of questions below, if you have the time, I would really appreciate your feedback.I will be using windows instead with the other two libraries, can I ask you, will your processing patch work with the other processing libraries?Also, I will be compositing the final video on Resolume, so I was thinking of sending the image from Isadora to Resolume via Syphon. Is it possible to keep the alpha values intact when importing the syphon image to Resolume.A huge thanks for your help. -
@DusX thanks for sharing. As I'm totally new to windows, I'll ask you something a bit dumb, what do I have to do to run this app?

– first question: I am more accustomed to MacOs, but I use windows on Bootcamp and I tried Kinect on W and M, with Processing and Touch Designer. For what I see it's much better implemented in Windows and with Windows Processing Kinect Library, you can obtain directly a mask to make background replacement. But you have to struggle with Spout who is less easy to use that Syphon (DirectX dependent, Graphic card dependent…).For my actual usage (https://vimeo.com/194632092) I use Processing and Isadora on MacOs with Syphon to pass image in both ways).– To use my patch with other library, you have to change all what is related to the library and I dont know how to obtain "getRawDepth"– For the second question, if you use Windows, you dont use Syphon but Spout… Concerning Syphon, if you declare your background in Processing with alpha mask (as color(0, 0, 0, 0), you send alpha with Syphon but I dont know about Resolume and Spout…In Millumin you have a quite easy way to obtain alpha mask from Kinect, give a try to the beta release.Jacques
