Robust Impulse Noise Variance Estimation Based on Image Histogram


The state of the art impulse noise removal methods make use of the noise variance, or equivalently the noise mixing probability <i>p</i>, and are iterative procedures (e.g., , ). However, so far there has been a lack of effective estimator for <i>p</i>. As a result, true values of <i>p</i> are often used during simulation, which may not be practical… (More)
