  1. What happens if we allow the color component to #diffuse out of the #MonaLisa?

    In this experiment, the #pixels of the Mona Lisa supply us with initial #RGB color component values, ranging from 0 to 255 (256 possible states for each component, for each pixel, at time t = 0).

    We then allow the red color component to diffuse out, according to the #HeatEquation, ∆u = ∂u/∂t; we step forward in time, solving for all color component values u, at each spatial location (x, y) in the painting 🖼 (along the edges of the painting, color components are held constant, so that we have a well-defined boundary value problem).

    We can see here what happens to the image as the red component diffuses out.

    Enjoy!
