In this context, the High Pass filter retains only the high-frequency components of the image, effectively removing smooth gradients and leaving edges and fine details. Mathematically, it approximates the computation of local spatial derivatives or Laplacians, which govern the diffusion component of the reaction-diffusion equations.
Conditions: Radius is set to 6.0 Pixels.; Applied after the Add Noise filter.
