Method for correcting artefacts in a digital image |
摘要 |
<p>A method of correcting artefacts in a processed digital image represented by a multi-scale gradient representation being obtained by non-linear processing of a multi-scale gradient representation of an original image. A modified gradient representation is generated by modifying gradient images of the multi-scale gradient representation of the processed image so that the directions of the gradient images are pixel-wise equal to those of the gradient images of the multi-scale gradient representation of the original image. A reconstruction algorithm is then applied to the modified gradient representation. <IMAGE></p> |
