Abstract

A mediolateral oblique (MLO) mammogram image contains far more than just an image of the breast. A film clip is generally present along with imaging artefacts and background noise. Before any computer analysis of the mammogram begins, the identification and extraction of the breast area is necessary a technique called global segmentation. This paper describes in detail a fully automated algorithm for global segmentation of MLO mammograms to create an accurate breast region without user intervention.
