Abstract:
A method of processing a digital signal representation of an original image comprising the steps of:1)--applying a decomposition transformation to said image to transform it into a decomposed image comprising a sequence of detail images at multiple successively lower spatial resolution levels and a residual image at a still lower resolution level, wherein each detail image represents the amount of local variation of pixel values within said original image at the resolution level of the detail image and wherein a residual image is an approximation of said original image with omission of all variations comprised in said detail images,2)--storing said detail images and said residual image into a memory,3)--retrieving from said memory detail images up to a predetermined resolution level among said multiple resolution levels, and said residual image,4)--processing retrieved detail images in accordance with a set of processing parameters,5)--generating a reconstructed image by applying the inverse of the decomposition transformation to the images processed in step 4 and to the residual image,6)--displaying said reconstructed image and evaluating it,7)--amending the numerical values of said processing parameters based on the result of said evaluation and repeating method steps 3 to 6 until the result of said evaluation satisfies an operator.
