Filter Node
![Filter Node.](../../../_images/compositing_node-types_CompositorNodeFilter.webp)
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.
Properti
- 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.
