Comp Vis is a computer vision re-interpretation of Norman McLaren's 'Synchronomy'.
The visuals of the original work are composed by photographing the film's optical soundtrack, creating synchrony between image and sound.
Comp Vis uses computer vision to identify 'areas of interest' in the original work, multiplying this selected area across the screen.
A soundtrack is generated from this re-composed image, using the brightness of the image in two ways; the deviation in frame brightness from a running average dictates the main tone, with the lower bass tone mapped to the unprocessed frame brightness value.
This re-interpretation preserves the audio and visual linkage of the original, while delegating the visual selection and construction of the image to the computer vision algorithm.
