**What it does**

<![CDATA[
Adds noise to or removes noise from images.

- **Add Random Noise** - Adds random noise to the image. The noise is Gaussian (normally) distributed with a mean of zero and standard deviation of 25.
- **Add Specified Noise** - Adds Gaussian noise with a mean of zero and a chosen standard deviation.
- **Salt and Pepper** - Adds salt and pepper noise to the image by randomly replacing 2.5% of the pixels with black pixels and 2.5% with white pixels. This command only works with 8-bit images.
- **Despeckle** - Replaces each pixel with the median value in its 3 × 3 neighborhood. This is a time consuming operation because for each pixel, the nine pixels in the 3 × 3 neighborhood must be sorted and the center pixel replaced with the median value (the fifth).
- **Remove Outliers** - Replaces a pixel by the median of the pixels in the surrounding if it deviates from the median by more than a certain value (the threshold).
- **Remove NaNs** - Replaces NaN (Not-a-Number) pixels in 32-bit images by the median of the neighbors inside the circular kernel area defined by Radius. It does not remove patches of NaNs larger than the kernel size, however.
- **RandonJ Binomial** - Contaminates image with random numbers generated using a binomial random variable
- **RandonJ Exponential** - Contaminates image with random numbers generated using an exponential random variable.
- **RandonJ Gamma** - Contaminates image with random numbers generated using a gamma random variable.
- **RandonJ Gaussian** - Contaminates image with random numbers generated using a Gaussian random variable.
- **RandonJ Poisson** - Contaminates image with random numbers generated using a Poisson random variable.
- **RandonJ Uniform** - Contaminates image with random numbers generated using a uniform random variable.
