Second Machine Portrait

This is the second portrait produced by the machine. The stroke resolution is quite low and the result is quite abstract. The painting highlighted a major area for improvement in the definition of the brush pressure profile:

  • Currently the pressure of the brush during a stroke varies¬†along the length of the stroke, but going forward it should also vary depending on how much paint is on the brush and potentially also the relative importance of each individual stroke.

Below I’ve presented a couple of additional images to show some of the key steps. There is also a video showing the machine painting process:

First Machine Portrait

This is the first portrait painted by the machine. It contains less than 200 brushstrokes and was used to test

  • How the machine loads paint onto the brush
  • The variation of stroke pressure over the course of a brush stroke.
