Witrynaimage noise is the so-called impulse noise. There are two types of this noise, which is salt and pepper noise and random valued noise. Median filtering is a nonlinear operation to reduce impulse noise. In salt and pepper noise the corrupted pixels take the maximum value or the minimum value which leads to white and black spots in the … 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 …
