摘要: A new method for impulse noise removal is presented, where a robust estimator of the variance, MAD (median absolute deviations from median), modified and used to efficiently separate noisy pixels image details. The algorithm free varying parameters, requires no previous training or optimization, successfully removes all types noise. pixel-wise concept straightforward, low in complexity, achieves high filtering performance.
