Filter Node

Filter Node.

The Filter node implements various common image enhancement filters.

Inputs

Factor
Controls the amount of influence the node exerts on the output image.
Image
Standard image input.

Properties

Type

The Soften, Laplace, Sobel, Prewitt and Kirsch all perform edge detection (in slightly different ways) based on vector calculus and set theory equations.

Soften
Slightly blurs the image.
Sharpen
Increases the contrast, especially at edges.
Laplace
Softens around edges.
Sobel
Creates a negative image that highlights edges.
Prewitt
Tries to do Sobel one better.
Kirsch
Giving a better blending than Sobel or Prewitt, when approaching an edge.
Shadow
Performs a relief, emboss effect, darkening outside edges.

Outputs

Image
Standard image output.

Example

The Filter node has seven modes, shown here.
