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 color 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.

Box Sharpen:

Increases the contrast, especially at edges.

Diamond Sharpen:

Less aggressive than box sharpen, reducing sharpening artifacts.

Laplace:

Edge highlighting filter susceptible to highlighting visual noise.

Sobel:

Creates a negative image that highlights edges.

Prewitt:

Produces a similar results to Sobel.

Kirsch:

Gives better blending than Sobel or Prewitt, when approaching an edge.

Shadow:

Performs a relief, emboss effect, darkening outside edges.

Outputs#

Image

Standard color output.

Example#

The Filter node has eight modes, shown here.#
