Impulse noise salt and pepper

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. An effective noise reduction method for this type of noise is a median filter or a morphological … Witryna4 lip 2024 · Digital images may suffer from impulse noise, including salt-and-pepper noise. One of the common methods to deal with this noise is by using median filter, which is a type of non-linear filter. Standard median filter includes noisy pixels in calculating the median value for the restoration process.
