Model-based adaptive algorithms are usually derived with the help of the Wiener-Hopf equation based on empirical statistics. They are often interpreted as an extension to their model-independent counterparts, i.e. the stochastic-gradient based adaptive ...

An improved adaptive median filter is proposed to remove the salt and pepper noise. The algorithm determines a pixel point as signal pixel or possible noise pixel according to the characteristic of the salt and pepper noise, the noise pixel is removed ...

Existing state-of-the-art switching-based median filters are commonly found to be nonadaptive to noise density variations and prone to misclassifying pixel characteristics at high noise density interference. This reveals the critical need of having a ...
