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.
