Breast Cancer Diagnosis in Mammograms Using Multilevel Wavelet Analysis

A computer aided diagnosis system based on multiresolution
analysis using the wavelet functions for interpreting
digital mammograms is introduced and tested. The goal is to
increase the diagnostic accuracy as well as the reproducibility of
mammographic interpretation. This system is based on extracting
an amount of the biggest coefficients in each level of a multilevel
decomposition. A set of images from MIAS (Mammographic
Image Analysis Society) database is used in evaluating the system.
