Abstract

In this work we employ an anisotropic smoothing filter based on partial differential equations (PDE) as a preprocessing step for the detection of suspicious regions in mammograms. The filter to be used at the present work, preserves the region boundaries while smooths homogenous regions. The proposed method has been tested with a dataset of 56 images from the mini Mammographic Image Analysis Society (MIAS) database and 30 images selected from the Digital Database for Screening of Mammography (DDSM). The method is evaluated in terms of the number of true-positive detection and the rate average of false-positive per image with good results.
