I Really like the concept to turning a solid wall into something more then it is. In this case the wall is an interactive canvas on which you use your body to create or animate a random objects.

On Computer Vision, body manipulation of digital media.

rafael.vargas@iaac.net — Wed, 21 Nov 2012 13:57:18 +0000

When looking for examples of computer vision projects I found out of the importance of the human body and the performance it will have interacting with digital media. While computer vision deals greatly with recognizing ‘objects’, the identification of human body could have very interesting applications. For instance, this installation called ‘body paint’ is designed to work with any number of people and is scalable to cover small or large areas. The interaction is very simple – movement creates paint. Hidden in the simplicity, are many layers of subtle details. Different aspects of the motion – size, speed, acceleration, curvature, distance all have an effect on the outcome – strokes, splashes, drips, spirals – and is left up to the users to play and discover.

On the other hand there is this very simple and fun project called ‘Body Swap’. This installation transforms your body movements into control of another person. Dance around, jump in the air, do anything you like to make them look silly.
Two people stand in front of the screen, are captured by the camera and turned into paper cut-out versions of themselves. The images are then swapped, so that you each take control of the other. The aesthetic is of a low polygon 90′s video game. Music plays and prompts you to act out to the audience and each other.

After our first ‘Computer Vision’ class, looking for tracking applications I found this simple and nice installation.

computer vision. Soak, Dye in light

antanaityte.gerda@iaac.net — Wed, 21 Nov 2012 11:28:00 +0000

“Soak, Dye in light.” by everyware (2011) is an empty canvas but when you touch it, its elastic surface stretches and gets suffused with projected vivid colors mimicking fabric absorbing dye. Poking and rubbing with hands or resting their body on this spandex canvas allows visitors to soak this canvas in virtual dye and create own patterns.

Computer Vision / Interstitial Fragment Processor

martin.lukac@iaac.net — Tue, 20 Nov 2012 09:24:03 +0000

A synaesthetic realization of the latent mass within negative spaces, the Interstitial Fragment Processor collects and drops the contoured shapes formed within and between the bodies of its participants. Elastic red and blue animated objects plummet toward the gallery floor, producing audiovisual improvisations on vertical descent and collision.

Computer Vision / Eyecode 2007

martin.lukac@iaac.net — Tue, 20 Nov 2012 09:05:20 +0000

Eyecode (Golan Levin, 2007) is an interactive installation whose display is wholly constructed from its own history of being viewed. By means of a hidden camera, the system records and replays brief video clips of its viewers’ eyes. Each clip is articulated by the duration between two of the viewer’s blinks. The unnerving result is a typographic tapestry of recursive observation.

computer vision. ping

antanaityte.gerda@iaac.net — Mon, 19 Nov 2012 18:49:52 +0000

PING is a low-tech augmented reality videogame that overlays a moving pixel to a videosignal. The pixel bounces off from objects that are darker than a specific threshold value. More about this projects at http://www.niklasroy.com/project/101/PING

computer vision. the cage

antanaityte.gerda@iaac.net — Mon, 19 Nov 2012 18:04:51 +0000

“La Gabbia” (The Cage) by auroraMeccanica (2011) is an installation that uses projection to invite the public to interact with physical bird cage to trigger the release of projected birds. At the center of a darkened room, a birdcage hanging from the ceiling it’s lit only by the white beam of the projector and its on the wall. Uncover the bird’s presence through playing a game, a very simple game in which we just have to push the cage and shake it.

I found this beautiful project here

My favorite computer vision project

balcaen.bert@iaac.net — Mon, 19 Nov 2012 16:44:58 +0000

My all-time favorite computer vision project is Text Rain by Camille Utterback & Romy Achituv. Hard to believe that this was done in 1999, long before the Kinect made this much easier.

It was created at ITP, and when I had the chance to spend some time there I did small hommage to this installation. This version uses a Kinect and Box2D. Creative Applications has a nice tutorial on how to do this in Processing.

Face recognition

balcaen.bert@iaac.net — Mon, 19 Nov 2012 16:19:49 +0000

The Viola-Jones algorithm is one of most common computer vision techniques to detect faces. Greg Borenstein did a nice interview with Adam Harvey where they talk about the underlying assumptions in the technique. Everything is explained clearly, so it’s great if you want to learn a little more about what happens behind the scenes.

Harvey did some interesting work on how we can circumvent face detection using makeup and hairstyles.
