| 摘要 |
The invention relates to a method of filtering an image dataset, having the following steps: providing an N-dimensional input image dataset (30) containing image data in the form of pixel/voxel values; applying a filtering algorithm (31) to the input image dataset (30), wherein the filtering algorithm is essentially unvarying over the dataset, to thereby obtain a filtered image dataset (32); providing a spatially varying weighting function (34) between the input and the filtered image datasets, the spatially varying weighting function being independent of the pixel/voxel values; computing (33) a weighted sum of the input image dataset and the filtered image dataset, thereby using the spatially varying weighting function (34), in order to obtain an output image dataset (36). The invention is also directed to an apparatus, a data carrier and a computer program product.
