QUANTIZATION IN MOTION visualizes the effects of pushing key components of JPEG compression (DCT
) beyond an ideal
state. This results in a stable glitch, making a transparent process opaque and demonstrates the rich set of aesthetics a digital image holds within.
This work technically began in 2008 while first investigating the effects of modifying the JPEG image header, specifically the quantization tables
, while beginning my masters thesis, Precise Mishandling of the Digital Image Structure
. This was first done with single images
, followed by one early attempt to build all 256 possible hex variations from 1 of 64 offsets including all 15 frames of The Horse in Motion
manually– however that study ended following a severe hard drive crash. In the end, HEADer_REMIX
was built as a tool to enable one to explore and exploit this region amongst others within the JPEG header.
QUANTIZATION IN MOTION is a return to an interest in mapping out all visual possibilities from 64 quantization offset regions, each containing 255 byte variations*
, across 15 frames of animation = 244,800 images. The images of each offset region have then been compiled into separate movie clips, showing the gradual transformation from ideal » extreme compression. This exercise in perverted pixel perfection
wouldn't have been possible without a handful of amazing open source tools: [Processing
I hope that this serves as a useful tool for the curious and gives the profound photography of Edward Muybridge
a relevant home in our digital realm.
