How does salt and pepper noise occurs in an image

Salt and pepper noise is an impulse type of noise in images. This noise is generally caused by errors in data transmission, failure in memory cell or analog-to-digital converter errors. It takes the form of randomly occurring white and black pixels, which can significantly deteriorate the quality of an image.

How can we add salt and pepper noise in an image?

By randomizing the noise values, the pixels can change to a white, black, or gray value, thus adding the salt and pepper colors. By randomizing which pixels are changed, the noise is scattered throughout the image. The combination of these randomizations creates the "salt and pepper" effect throughout the image.

How can the salt pepper effect in an image be reduced?

It presents itself as sparsely occurring white and black pixels. 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.

Which operator method is best of salt & Pepper noisy image and why?

The standard median filter is a typical nonlinear filtering method with a simple idea and fast processing, which is most suitable for processing impulse noise such as salt and pepper noise.

Is salt and pepper An impulse noise?

Salt-and-pepper noise, also known as impulse noise, is a form of noise sometimes seen on digital images. This noise can be caused by sharp and sudden disturbances in the image signal. It presents itself as sparsely occurring white and black pixels.
