Abstract :
This paper presents a new adaptive filtering algorithm for image enhancement basing on several image enhancement algorithms, under α stable impulsive noise. The algorithm defines a new fractional lower order moment to adjust the weight of adaptive filter. It has a better robustness to impulsive noise. Simulation results show that the new algorithm is more effective to restrain spike noise under proper parameter compared with traditional algorithm based on a stable impulsive noise.
