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.
