Abstract
A method of filtering an image dataset and an apparatus, a data carrier, and a computer program product, the method having the following steps: providing an N-dimensional input image dataset; applying a filtering algorithm to the input image dataset, wherein the filtering algorithm is essentially unvarying over the dataset, to thereby obtain a filtered image dataset; providing a spatially varying weighting function between the input and the filtered image datasets; computing a weighted sum of the input image dataset and the filtered image dataset, thereby using the spatially varying weighting function, in order to obtain an output image dataset.
