RemoveSaltPepperCommand Class

Summary

Removes the salt and pepper noise from the specified image.

Remarks
  • This command takes an image and removes salt (pixels having a value of 255) and pepper (pixels having a value of 0) and replaces them with the median value of the non-noisy pixels around them.
  • This command works only on 8-bit images.
