Denoiser node — Material Maker documentation

# Denoiser node

The Denoiser node performs fast spatial deNoise filter, with circular gaussian kernel.

## Inputs

The Denoiser node accepts one input:

- The Source inputs is the image to be denoised.

## Outputs

The Denoiser node outputs the denoised image.

### Parameters

The Denoiser node has the following parameters:

- the Size determines the resolution of the denoiser

- the Standard Deviation Sigma radius

- the kSigma is the K factor sigma coefficient:

    - kSigma = 1*sigma cover 68% of data

    - kSigma = 2*sigma cover 95% of data - but there are over 3 times more points to compute

    - kSigma = 3*sigma cover 99.7% of data - but needs more than double the calculations of 2*sigma

- the edge Sharpening threshold
