Face detection in izzi

During the research of our last project I did a quick test with a quartz composer actor inside Isadora http://youtu.be/Wcsr85QQn0M Greetings, Alex

Fred, thanks for taking the time.

I saw your presentation in TED Netherlands, and it is amazing, not because the technological "device" (witch is very nice, of course) , but because of content, design and performance. really really nice.

I think we will try to solve the problem outside izzi and send osc and syphon data to izzi. I have to make some test. What we need to archive could be quite rough actually.

@feinsinn what is that actor?

Thanks again

@deliriodelux cool gald you saw it. We used standard face detection from open CV to do that. We could get up to 700 faces in a single shot. We tricked everyone to look at the camera. In the end I think I got about 80% success but we had to have a system for correcting false positives (many for some reason this library finds cleavage as a face a lot), and to add the faces it missed. Let me know how you go and if you need anything made to bridge the gap to Izzy. Fred

@deliriodelux there is a tutorial here http://vdmx.vidvox.net/tutorials/making-face-tracking-fx-for-vdmx-with-quartz-composer on using the (face) Detector in Quartz Composer.
After building it in QC, to use the QC patch in Isadora, you would publish the inputs and outputs that you need on the Quartz Composer modules and then place the QC Composition file into the right directory (as defined in Isadora's preferences window) and then Izzy will load the QC patch as a plugin, when it boots up.

@fred, yes i saw those false positives too, the corrections were very well hidden ! To have a MC like that helps a lot! Thx for the tips and i let you know if get lost on the way..

@primaldevine, cool thx ! , I did Qc input-output publishing before, ....well.. actually is already done. Its in the downloadable folder of from the tutorial.

I let you now how it goes.

Long life to the izzi forum!

There was a build called FACE OSC I had working a while ago.

I also had something working with Quartz but can't remember the name....

Has anyone ever got this to work?

I downloaded it, put it in its place but Izzy can't see it.

@ skulpture i have the same problem. i was quite exited when i found it but it does not show up in izzy :(

Same - tried a few things but I think it needs updating.
