# Noise Image

Class: NodeNoiseImageFilter

Calculate the local noise in an image.

Computes an image where a given pixel is the standard deviation of the pixels in a neighborhood about the corresponding input pixel. This serves as an estimate of the local noise (or texture) in an image. Currently, this noise estimate assume a piecewise constant image.

## Inputs

#### Image

An image.

Type: Image4DFloat, Required, Single
