Median (Median)
Compute the median scalar values in a specified neighborhood for image/volume datasets.
The Median filter operates on uniform rectilinear (image or volume) data and produces uniform rectilinear output. It replaces the scalar value at each pixel / voxel with the median scalar value in the specified surrounding neighborhood. Since the median operation removes outliers, this filter is useful for removing high-intensity, low-probability noise (shot noise).

Input
(Input)
This property specifies the input to the Median filter.  

The selected object must be the result of the following: sources (includes readers), filters.

The dataset must contain a point array with 1 components.

The selected dataset must be one of the following types (or a subclass of one of them): vtkImageData.

 
Kernel Size
(KernelSize)
The value of this property specifies the number of pixels/voxels in each dimension to use in computing the median to assign to each pixel/voxel. If the kernel size in a particular dimension is 1, then the median will not be computed in that direction. 1 1 1  
Select Input Scalars
(SelectInputScalars)
The value of thie property lists the name of the scalar array to use in computing the median.  

An array of scalars is required.
