How to perform morphological mean filter to remove impulse noise

[Image Analyst]

What is a morphological mean filter? I've never heard of it.

[Shehin Shams P]

Sir, Here i am attaching the paper of Morphological Mean Filter. Do you have any idea about implementing an impulse noise removal method by using morphological dilation operation.

[Shehin Shams P]

sir, Can you help me?

Other than spending hours reading and understanding the article, and coding it up and testing it ( http://matlab.wikia.com/wiki/FAQ#Can_you_program_up_the_algorithm_in_this_article_for_me_and_explain_it_to_me.3F ), what kind of help do you want/expect?

Answer 1

See my salt and pepper noise removal demo. It finds slat and pepper noise and replaces only those noise pixels with the median value of the neighborhood around the noise. Please mark the answer as Accepted if it does what you want.

There is a new function added in R2018b: imnlmfilt().

It does non-local means denoising, which is generally regarded as one of the best image denoising filters out there.

I'm also attaching a Kuwahara filter demo, which is an edge preserving denoising image filter.
