Animated visualization of 2D cross advection approach, with injected dye and sparse noise injection. The error threshold is maipulated by the user, changing the visualization from clear streaklines to blured streaklines perpendicular to the flow.

Film of 2D advection with applied Gaussian error diffusion. Constantly changing the error threshold affects the diffusion of the streaklines in error affected regions.

Animation of the multi-frequency advection. Spatial frequencies are altered by uncertainty magnitude.
