Filter control via light blob tracking in Processing

Brilliant example on setting and controlling a filter’s parameters via MIDI mapping, creating a control surface via a webcam and a torch by Daniele Mattei (Youtube). News via blog.lecollagiste.com

Daniele Comments:

I realised a little Processing sketch that tracks the light blob I shot in front of webcam, normalises X and Y coordinates to MIDI acceptable values, and then sends them to a filter effect in Ableton Live.

I also realised the little control panel that allows to correctly make the MIDI mapping and set some blob detection’s params.

My toolkit:
Processing.org
MIDI: theMidiBus Processing‘s library
blob detection: openCV Processing‘s library
GUI: controlP5 Processing’s library
Ableton Live

Software might be released soon, depending on conditions given from University where Daniele Mattei is undertaking a study.
