Breast region segmentation is an essential prerequisite in the (semi-)automatic analysis of digital or digitised mammographic images, which aims to separate the breast region from background information in mammograms. It normally consists of two independent segmentations, which are breast-background segmentation and pectoral muscle segmentation, respectively. The first identifies the boundary between...
This paper presents a novel method for breast density segmentation in mammograms. The global structure of dense tissue is analysed based on a topographic map of the whole breast, which is a hierarchical representation, obtained from the upper level sets of the image. A shape tree is constructed to represent the topological and geometrical structure of the topographic map. The saliency and independency...
