CONTINUOUS EXTENSION OF DISCRETE TRANSFORM FOR DATA PROCESSING

摘要

A method for interpolating images using continuous extension functions of inverse discrete transformation is described. The method comprises defining at least one block of an image dataset and calculating and storing forward discrete orbit function transform coefficients representing the at least one block. The method involves defining a first and second different spatial resolution and calculating a first processed image dataset using at least one continuous extension of discrete orbit function transform representing said at least one block using the stored discrete orbit function transform coefficients and the first different spatial resolution. A second processed image dataset is calculated using at least one continuous extension of discrete orbit function transform representing said at least one block using the stored discrete orbit function transform coefficients and the second different spatial resolution.
