Oh, don’t act all surprised and shocked. You know you’d go and do the same thing if you had access to a thermo camera.

Bartek Polonski sends us an unusual twist on computer vision, combining thermography with basic code in Processing in order to subtract water from the scene. (No details on the specific camera – anyone familiar with available cameras for this task?) Thermal cameras are used in airports and such, but as a visual tool it takes on a different function.

Bartas explains:

It’s so simple, some processing blob tracking code i wrote in few minutes. Even fade out effect is not because of the code but because water becomes colder starting from the edges of water splash and becoming colder inside the splash, so hot blob becomes smaller and smaller 🙂

Here’s a lovely example of the subtraction at work:
