Gauss Filter
The Gauss Filter can be applied to the 3D image to remove noise or to smooth the image.
Sphere Radius defines the size of the neighborhood used for filtering the 3D image. The radius is specified in voxels and determines the extent of the Gaussian kernel applied to the image.
Sigma specifies the standard deviation of the Gaussian filter in voxels and controls the amount of smoothing. Larger sigma values result in stronger smoothing and noise reduction, while smaller values preserve more image detail.
After adjusting the parameters, click Apply to filter the image using the current settings.
Please refer to the Median Filter page for an example. You can achieve similar results using the Gauss Filter with the same sphere radius value.
