Filter Node

The Filter node implements various common image enhancement filters.

Входы

Коэффициент (factor): Управляет степенью оказываемого узлом влияния на выходное изображение.
Изображение (image): Стандартный ввод цвета.

Свойства

Тип (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.
Тень (shadow): Performs a relief, emboss effect, darkening outside edges.
