Bilateral Blur Node

Bilateral Blur Node.

The Bilateral Blur node performs a high-quality adaptive blur on the source image, allowing to blur images while retaining their sharp edges.

It can be used for various purposes like: smoothing noisy render passes to avoid longer computation times in example ray-traced ambient occlusion, blurry refractions/reflections, soft shadows, or to make non-photorealistic compositing effects.

Entradas

Imagen

Entrada de color estándar. Si sólo se conecta la entrada de la imagen, el nodo desenfoca la imagen según los bordes presentes en la imagen de origen.

Determinator

Which is non-obligatory and if the Determinator is connected, it serves as the source for defining edges/borders for the blur in the image. This has great advantage in case the source image is too noisy, but normals in combination with Z-buffer can still define exact borders/edges of objects.

Propiedades

Iteracciones

Defines how many times the filter should perform the operation on the image. It practically defines the radius of blur.

Color Sigma

Defines the threshold for which color differences in the image should be taken as edges.

Space Sigma

A fine-tuning variable for blur radius.
