摘要
A method the generating a first plurality of output data values and the matrix factors used to generate an approximation to an image processing transforming a plurality of input data values using a computer and applying a modified (260) transform stored in a modified transformation matrix to the plurality of input data values. The plurality of input data values are stored in a generated matrix, and at least one data values in this matrix is rearranged (240) using a permutation operation and modified by applying a linear combination (270) of the unmodified values to the at least one data value.
