Filter

Applies standard filters to image data.

Input

One or more images or volumes or sets thereof. If multiple inputs are present they need to be of the same kind, it is not permissible to e.g. mix images and image sets or images and volume.

Output

Will create a filtered copy of the input image if the create new check box is enabled. Otherwise, will modify the input image.

Description

The user can select from the following list of available filter algorithms:

  • Sharpening: Applies an unsharp mask filter to the input image. The Kernel Radius parameter defines the size of the filter, the Scaling Factor parameter defines the strength of the sharpening effect.
  • Smoothing: Applies a Gaussian smoothing filter to the input image. The Kernel Radius parameter defines the size and strength of the smoothing effect.
  • Guided Filter: Applies the guided filter to the input image.
  • Anisotropic Diffusion: Applies an edge-preserving smoothing filter to the input image using explicit-scheme anisotropic diffusion. The given kernel size is in pixels.
  • Bilateral Filter: Applies an edge-preserving bilateral smoothing filter to the input image.
  • XClahe Filter: Applies the contrast-enhancing XClahe filter to the input image. Only available for 2D input.
  • Uniform Noise: Adds uniform noise to the input image.
  • Gaussian Noise: Adds Gaussian noise to the input image.
  • Poisson Noise: Adds Poisson noise to the input image.
  • Gradient: Computes the gradient image of the input image.
  • Edge Filter: Applies a 3x3 Sobel edge filter to the input image.
  • Median Filter: Applies a median smooting filter to the input image.
  • ADSOC: Applies the ADSOC sharpening filter to the input image as described in this PDF.
