I’m just rushing out the door off to Glastonbury to set things up.. I thought you might be interested in this little (!) project…
Glastonbury 2008 PI Teaser (Webcam Piano + Psychedelic Fluids) from Memo Akten on Vimeo.
Everything is entirely camera driven and realtime. Originally started this app in processing, but realized I needed as much power as possible so switched to C++ / OpenFrameworks. Not using the GPU as much as I’d liked due to time restraints, v2 will be fully GPU hopefully

Anyone going to Glastonbury? Drop in and play Memo’s piano for us. Working on your own (little!) project? Contact form‘s to the right.

I could spend hours playing with something like this.
Beautiful!
wow, leave to memo to combine my two favorite projects of his!
Nice work my friend keep it up!
that boy memo is too clever by half.. pith i can't make it to glasto this year…
wow… i want to play with it!
D'oh! Figures that it'd be on the year that I don't go!
Love his stuff. Can see why he needed to use C++ though. I tried getting a similar movement detection working in processing- I had frame differencing set up and then ran the image through a threshold filter, but in order to cut down on camera noise, I added gaussian blur before thresholding. Ran really slowly.
I love the way that memo has put this together though!
CongoZombie: I'm not that really that much into codding so the following statement is just me being a smart ass. Might even completely not know what I'm talking about
2 years ago I saw a guy that use an eroding technique to remove the noise. I think he first detected possible shapes than he remove 1 or more pixels around the shape in order to eliminate shapes created by noise. I think that method was much faster than applying a blur.
