Question

What is salt and pepper noise. How can you remove salt and pepper noise?

Answer 1

Answer:

Salt-and-pepper noise is a form of noise sometimes seen on images. It is also known as impulse noise. ... An effective noise reduction method for this type of noise is a median filter or a morphological filter. For reducing either salt noise or pepper noise, but not both, a contraharmonic mean filter can be effective.

Answer 2

Salt-and-pepper noise is a form of noise sometimes seen on images.

Use the Median Filter block to eliminate the black and white speckles in the image. Use the default parameters. The Median Filter block replaces the central value of the 3-by-3 neighborhood with the median value of the neighborhood. This process removes the noise in the image.
