摘要：At least one approximation image is created of the image at one or multiplescales. Translation difference images are created by pixel-wise subtracting the values ofan approximation image at scale s and the values of a translated version of the

approximation image. A non-linear modification is applied to the values of the translationdifference image(s) and at least one enhanced center difference image at a specific scaleis computed by combining the modified translation difference images at that scale or asmaller scale with weights w. An enhanced image is computed by applying areconstruction algorithm to the enhanced center difference images. The non-linearmodification of the values of the translation difference images is steered by

(a)characteristic(s) computed out of the approximation image(s) at at least one scale.
