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.
