For my Computer Vision exercise I decided to work with Multi Blob Tracker Library (Flob)
http://s373.net/code/flob/flob.html designed by Andre Sier and using the Flood Fill
Algorithm. The result is a fluffy cluster of elements resembling the poplar or dandelion seeds,
moving, drifting, floating and clustering according to a tracked movements of a person sitting
in front of a web camera.

AntiMap Workshop / Data visualization
Using the Antimap application we are able to record a data file representing our journey.
The csv. file contains information such as your position ( latitude and longitude), your
orientation towards the north (compass), data representing your speed in kilometers per
hour, direction and time of the journey measured in milliseconds.
My intention was to create a visual representation of each piece of data distinctly, so it
would be easier to understand that the final trajectory contains all the above-mentioned
data. From a more narrative and static representation of each data set in the beginning
of the workshop I decided to follow more abstract way of representation, using the simple
geometry of lines and shapes, playing with colors and transparency.
The final visualization draws the lines from data points like threads, weaving each
data line into the trajectory of movement. This forms a visual fabric covering the whole
area of canvas during a period of time. I used the csv. files from two distinct sources
in order to test a diverse visual qualities, resulting in repetitive but different patterns.
Computer Vision / Interstitial Fragment Processor
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
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.

subjective clock
Hours are represented by a horizontal/RGB pixel scale (one pixel=1 hour), minutes are represented by a vertical/GRAYSCALE pixel scale (one pixel= 5 minutes) and seconds are represented by a diagonal/BINARY pixel scale (60 blinks per minute). Grayscale bar moves along the RGB scale, pointing to an hour pixel and binary scale moves along the grayscale, pointing to a minute pixel.
