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 as Sobel or Prewitt, when approaching an edge.
Shadow: Performs a relief emboss/ bumpmap effect, darkening outside edges.

Outputs¶

Image: Standard image output.

Example¶

The Filter node has seven modes, shown here.
