Diffusion Grayscale

In: Filters/Effects

Intermediate

Description

Apply a diffusion process to the values in Source image input according to the provided Mask image input, creating smooth gradations between values.

Only values from pixels matching the mask are diffused; other pixels don't participate in the result.

Parameters

  • Iterations: 0.0 - 64.0
    The number of diffusion iterations to perform (higher is better but slower). Useful values are in the [8, 48] range.
    Please note that if you are not looking for mathematical correctness, low values are fine or even better.
    Distance: 0.0 - 1.0
    Adjusts the maximum distance of the diffusion.
  • Enable Dithering: True/False
    Controls the sampling method of each pass. Dithering allows convergence in less passes, but introduces noise.
    Without it, each pass is faster but more passes are required to achieve a smooth result without banding artifacts.

Inputs

  • Source Grayscale
    The image to diffuse.
  • Mask Grayscale
    Diffusion mask: white pixels are sampled in Source and diffused in black pixels. The image should be black and white. If the mask includes gradients, the cutoff value is 0.5.

  • Intensity Grayscale
    Defines locally how strong the diffusion process is applied. This map should be contrasted for a noticeable effect.
