I projected some live reactive video filters for the Dragging an Ox through Water show last week. Above is a photo of the “Bubble Filter” in action. 

Above are stills from four of the filter modes. Modes can be selected by pressing the 1-5 keys or the “b” and “w” keys. The modes are as follows:

1: Unfiltered video
2: Black and White Bubble Filter
3: Colored Bubble Filter
4: Grey/Red Frame Difference Filter (based on the “Frame Differencing” sketch by Golan Levin)
5: Grey/Red Frame Difference Filter w/noise (based on the “Frame Differencing” sketch by Golan Levin)
B: Black screen
W: White screen

If you have a built in video camera on your computer, you can load up the sketch in Processing and start playing with live filtered video.
