Gaussian Filter

Features:

Removes spatial and spectral noise in the entire datacube by applying a Gaussian Filter. This filter is global and will be retained for all other functions and treatments.

Steps:

1.      Select Filtering and Enhancement → 3D Gaussian Filter.  

2.      After completion, click OK and visualize the filtered image.

3.      The filtered image can be returned to the original by using Filtering and Enhancement → Remove all Filters and Enhancements or Reset button.

Additional Information:

The algorithm filters the datacube with a 3D Gaussian smoothing kernel with a standard deviation of 0.5 and returns the filtered image. All voxels in the image must have values.
