Processing In Digito

Description

Processing In Digito is a series of pieces that incorporate photography and led lighting to create emotionally evocative images. Each piece is a photograph of a real life object, processed using digital image processing techniques in Processing, and then laser etched onto a piece of acrylic. The laser etched piece is then lit up using LEDs to give the piece a surreal visual aesthetic.

The ‘magic’ of this piece is done by clever photo processing to convert full-color images into black-and-white images ready to be raster etched in processing. Example filters have been posted to OpenProcessing:


Differential Photo Filter
Proportional Photo Filter

The name ‘Processing In Digito’ is a backronym for PID — an acronym that comes up frequently in feedback systems that stands for ‘Proportional, Integral, Derivative’ (typically used in the context of control loops). This piece uses Proportional and Derivative algorithms to process the photos (and I’m currently working on an integral one!).

Below are some images of the final LED pieces that were on display at MIT’s Wiesner Student Art Gallery in January 2012:
