Module Description

The MedianImageFilter is commonly used as a robust approach for noise reduction. This filter is particularly efficient against "salt-and-pepper" noise. In other words, it is robust to the presence of gray-level outliers. MedianImageFilter computes the value of each output pixel as the statistical median of the neighborhood of values around the corresponding input pixel.

Use Cases

Most frequently used for these scenarios:

• Use Case 1:

• 

  Input Image

• 

  Median Filtered Image
