Image Processing with Wreath Products

We present a technique to decompose digital images using generalizations of the Discrete Fourier Transform (DFT). This method arises from the representation theory of iterated wreath product groups, which describe symmetries of the quad tree decomposition of an image. In addition, we describe applications to compression, edge detection, and de-noising, as well as experimental results to evaluate the performance of these operations.
