Recently I uploaded a few little OpenFrameworks addons to Github; nothing special, but maybe someone could use them, so:

  • ofxVibe is a test implementation of the ViBE BG subtraction algorithm.
  • ofxIniParser, as its name suggests, is a tool for reading/writing ini files.
  • ofxBase64 is base64 encoder/decoder that includes a set of functions to embed/read ofPixels into xml files.
  • ofxAvailableSpace is just a quick way to check the available space in the file system.

I strongly believe in R/D and I strongly believe in the importance of academic research, so I’m kind of happy to share a little preview of contribute to the experimental work carried out by Parma University’s Neuroscience Department (yes! those rockstars who discovered mirror neurons!).
Here’s a short video demoing a software tool to be used in the scope of experiments on the perception of self. I’ll write more about it as the research progresses; for now let’s just say that the idea is measuring in a precise way how much a face needs to change for you to stop recognizing it.

First time on stage for Marco Tempest‘s last augmented reality trick!
The ingredients:

– augmented reality objects that interact with the performer using a combination of markerless and natural features based techniques

– fluid realtime full HD special effects using a bit of GPU voodoo

enjoy 🙂

If you watched the Magic and Storytelling video, you have probably noticed that Marco‘s face “magically” changes: as all computer vision nerds out there have already guessed, this was done using Jason Saragih’s awesome library. When the software for the performance was being written, this library had already been wrapped into a handy OpenFramworks addon (thanks Kyle and Arturo), but there wasn’t an easy way to use it from VVVV, so we created FreeFrame facetracking plugin.
Today Joreg officially released the plugin to the public and was kind enough to credit me in the release post; so if you’re into win visual patching, go get it!

I’m still playing with swappable faces and, in particular, I’m setting up a software tool to quickly create and customize synthetic faces that would fit like a glove (or should I say a balaclava?) on your natural one.
I needed to create a test model and, considering the average cultural feedback to this kind of technology, I thought that nobody would be a better candidate than Guy Fawkes:

Here’s the teaser for the performance I’ll present @ Borderline Biennale 2011 together with Stefano Moscardini and Lukas Zpira. There will be blood, steel, neural waves, computer vision and synths; if you can be around Lyon at the beginning of september, be there!

As you could imagine reading my last post, I’m working on an interactive floor using a projector + Kinect combo. It’s still early to speak about the final installation, but I just recorded a couple videos of the current beta and wanted to share them.
