Interpolation Plugin

This is an interpolation plug-in for the GIMP. It works by doing plane/curve fitting and calculating weighted averages. It takes samples from a grid of pixels from 'known' image areas, trying to fit a plane or a curve to each, and then uses those samples to estimate the 'unknown' image areas.

lower left: selection (a.k.a. output mask), lower right: input mask

Noise generator

This filter generates noise in an image. Available noise types are

  • Poisson noise
  • Gaussian noise
  • Uniform noise
  • Laplace noise
  • Lorentz noise
  • It is possible to generate (YCbCr) luminance noise only and to apply a gamma correction.

    General description

    This filter noisifies an image with different types of noise. For each noise type it's specific values can be set. These are
