The theoretical basis for an adaptive multiresolution and multiorientation wavelet transform methods for image preprocessing is described for improved CAD performance in breast cancer screening using digital maniinography. The method is an extension of an earlier method reported that uses fixed parameters for the multiorientation wavelet transforms. Simulation results are described to demonstrate the importance of using higher order transforms. The computed FROC results are summarized for the previously reported non-adaptive methods, compare well to that reported in the literature, to demonstrate the potential improvement if adaptive methods are used.
