A method for image data processing is disclosed, which includes multiplying each data element of a first group of image data with a corresponding rational dyadic constant of a first group of rational dyadic constants to produce first modified image data. Each rational dyadic constant approximates a corresponding irrational constant of a first group of irrational constants that are scaled by a first common factor. Each rational dyadic constant is a rational number having a dyadic denominator. |
