This is a project Kyle and I just finished working on.
It is an interactive photography installation that will run in Amsterdam till the end of September.

Blurb: Portrait Machine is an interactive photography installation that visualizes the connections between visitors. It makes these connections based on a number of features, such as clothing choice, hair color, facial expression, and composition within the frame. It presents both similarities and differences in these characteristics, remdining us of our connectedness and uniqueness, creating strong visual patterns and playful juxtapositions.

Lots of useful code came out of this project so look out for ofxExif, ofxCanonSDK, ofxFace and a bunch more!

Theo and Kyle

WOW SWEET

Adding to the addons Theo mentioned, ofxColor and ofxCvHaarFinder are already on the forums here

I'm still working on ofxKmeans, which uses OpenCV to automatically cluster an image/roi into N dominant colors (and return thresholded images for contour finding), or cluster ofPoints into N clusters.

really cool installation, congrats.
particularly looking forward to ofxCanonSDK and seeing what it can do.

congrats, nice project.

tried something similar but used facebook portraits therefore - didn't worked like i wished, mainly because the image segmentation to separate the people from the background is hard to handle.

Nice one guys, the images look great! Love the face finder triggering the shot too.

You could hire it out at events no problem, like this london photographer does with his booth...

What kind of background were you dealing with?

Here, the solid white wall and fairly controlled lighting help a lot -- but it still doesn't solve cases like this:



That's where OpenCV comes in handy

was using facebook 'friends' profile pictures. the backgrounds there are all fairly variable. was using open cv watershed algorithm and graphcut (http://people.cs.uchicago.edu/~pff/segment/) but both didn't produce satisfying results.

Currently it wraps the DSLR EDSK and does the following things (only tested on a Canon 450D).

Remote trigger.
Remote download.
Remote download and delete ( ie pull an image off a camera ).

Enable/Disable live view
Get live view stream as pixels (@ 848 by 576)
Download live view as image sequence (great for getting video out of non-video capable cannons).

Adding other commands is pretty straightforward we didn't need too much so I could see it being expanded.

Will get the code posted soon.
Theo

oh wow, the canon addon sounds good. Exact the think I need for my next installation looking forward to the release.

haha, those comps are ace, especially like the last one!

Great project, really love it.

Hey Theo,
Which Canon EDSDK did you use for EOS450D?
I can't seem to find one..

Hi !!

is there any chance to get the ofxCanonSDK??

Recently bought one Canon 5D and I want to try some features that you showed in your project, is really really interesting.


Congrats for your work!!

I'll let Theo post the Canon SDK wrapper (or at least code snippets?), since that was more his specialty. I also don't have a camera to test it on right now! Though last I checked, it was heavily intertwined with our specific use (implementing things like countdown-to-photo).

Actually, checking the list again, my G10 might be supported to some degree... I'll give that a shot.

Anyway, the FAQ from Canon is here:

http://www.usa.canon.com/consumer/controller?act=SDKHomePageAct&keycode=Sdk_Lic&fcategoryid=314&modelid=7474&id=3464

There's a compatibility list in the middle, and at the very bottom there's a link to the request form for an SDK copy.
